+ /**
+ * The embodiment of the adaptive LL(*), ALL(*), parsing strategy.
+ *
+ * <p>
+ * The basic complexity of the adaptive strategy makes it harder to understand.
+ * We begin with ATN simulation to build paths in a DFA. Subsequent prediction
+ * requests go through the DFA first. If they reach a state without an edge for
+ * the current symbol, the algorithm fails over to the ATN simulation to
+ * complete the DFA path for the current input (until it finds a conflict state
+ * or uniquely predicting state).</p>
+ *
+ * <p>
+ * All of that is done without using the outer context because we want to create
+ * a DFA that is not dependent upon the rule invocation stack when we do a
+ * prediction. One DFA works in all contexts. We avoid using context not
+ * necessarily because it's slower, although it can be, but because of the DFA
+ * caching problem. The closure routine only considers the rule invocation stack
+ * created during prediction beginning in the decision rule. For example, if
+ * prediction occurs without invoking another rule's ATN, there are no context
+ * stacks in the configurations. When lack of context leads to a conflict, we
+ * don't know if it's an ambiguity or a weakness in the strong LL(*) parsing
+ * strategy (versus full LL(*)).</p>
+ *
+ * <p>
+ * When SLL yields a configuration set with conflict, we rewind the input and
+ * retry the ATN simulation, this time using full outer context without adding
+ * to the DFA. Configuration context stacks will be the full invocation stacks
+ * from the start rule. If we get a conflict using full context, then we can
+ * definitively say we have a true ambiguity for that input sequence. If we
+ * don't get a conflict, it implies that the decision is sensitive to the outer
+ * context. (It is not context-sensitive in the sense of context-sensitive
+ * grammars.)</p>
+ *
+ * <p>
+ * The next time we reach this DFA state with an SLL conflict, through DFA
+ * simulation, we will again retry the ATN simulation using full context mode.
+ * This is slow because we can't save the results and have to "interpret" the
+ * ATN each time we get that input.</p>
+ *
+ * <p>
+ * <strong>CACHING FULL CONTEXT PREDICTIONS</strong></p>
+ *
+ * <p>
+ * We could cache results from full context to predicted alternative easily and
+ * that saves a lot of time but doesn't work in presence of predicates. The set
+ * of visible predicates from the ATN start state changes depending on the
+ * context, because closure can fall off the end of a rule. I tried to cache
+ * tuples (stack context, semantic context, predicted alt) but it was slower
+ * than interpreting and much more complicated. Also required a huge amount of
+ * memory. The goal is not to create the world's fastest parser anyway. I'd like
+ * to keep this algorithm simple. By launching multiple threads, we can improve
+ * the speed of parsing across a large number of files.</p>
+ *
+ * <p>
+ * There is no strict ordering between the amount of input used by SLL vs LL,
+ * which makes it really hard to build a cache for full context. Let's say that
+ * we have input A B C that leads to an SLL conflict with full context X. That
+ * implies that using X we might only use A B but we could also use A B C D to
+ * resolve conflict. Input A B C D could predict alternative 1 in one position
+ * in the input and A B C E could predict alternative 2 in another position in
+ * input. The conflicting SLL configurations could still be non-unique in the
+ * full context prediction, which would lead us to requiring more input than the
+ * original A B C. To make a prediction cache work, we have to track the exact
+ * input used during the previous prediction. That amounts to a cache that maps
+ * X to a specific DFA for that context.</p>
+ *
+ * <p>
+ * Something should be done for left-recursive expression predictions. They are
+ * likely LL(1) + pred eval. Easier to do the whole SLL unless error and retry
+ * with full LL thing Sam does.</p>
+ *
+ * <p>
+ * <strong>AVOIDING FULL CONTEXT PREDICTION</strong></p>
+ *
+ * <p>
+ * We avoid doing full context retry when the outer context is empty, we did not
+ * dip into the outer context by falling off the end of the decision state rule,
+ * or when we force SLL mode.</p>
+ *
+ * <p>
+ * As an example of the not dip into outer context case, consider as super
+ * constructor calls versus function calls. One grammar might look like
+ * this:</p>
+ *
+ * <pre>
+ * ctorBody
+ * : '{' superCall? stat* '}'
+ * ;
+ * </pre>
+ *
+ * <p>
+ * Or, you might see something like</p>
+ *
+ * <pre>
+ * stat
+ * : superCall ';'
+ * | expression ';'
+ * | ...
+ * ;
+ * </pre>
+ *
+ * <p>
+ * In both cases I believe that no closure operations will dip into the outer
+ * context. In the first case ctorBody in the worst case will stop at the '}'.
+ * In the 2nd case it should stop at the ';'. Both cases should stay within the
+ * entry rule and not dip into the outer context.</p>
+ *
+ * <p>
+ * <strong>PREDICATES</strong></p>
+ *
+ * <p>
+ * Predicates are always evaluated if present in either SLL or LL both. SLL and
+ * LL simulation deals with predicates differently. SLL collects predicates as
+ * it performs closure operations like ANTLR v3 did. It delays predicate
+ * evaluation until it reaches and accept state. This allows us to cache the SLL
+ * ATN simulation whereas, if we had evaluated predicates on-the-fly during
+ * closure, the DFA state configuration sets would be different and we couldn't
+ * build up a suitable DFA.</p>
+ *
+ * <p>
+ * When building a DFA accept state during ATN simulation, we evaluate any
+ * predicates and return the sole semantically valid alternative. If there is
+ * more than 1 alternative, we report an ambiguity. If there are 0 alternatives,
+ * we throw an exception. Alternatives without predicates act like they have
+ * true predicates. The simple way to think about it is to strip away all
+ * alternatives with false predicates and choose the minimum alternative that
+ * remains.</p>
+ *
+ * <p>
+ * When we start in the DFA and reach an accept state that's predicated, we test
+ * those and return the minimum semantically viable alternative. If no
+ * alternatives are viable, we throw an exception.</p>
+ *
+ * <p>
+ * During full LL ATN simulation, closure always evaluates predicates and
+ * on-the-fly. This is crucial to reducing the configuration set size during
+ * closure. It hits a landmine when parsing with the Java grammar, for example,
+ * without this on-the-fly evaluation.</p>
+ *
+ * <p>
+ * <strong>SHARING DFA</strong></p>
+ *
+ * <p>
+ * All instances of the same parser share the same decision DFAs through a
+ * static field. Each instance gets its own ATN simulator but they share the
+ * same {@link #decisionToDFA} field. They also share a
+ * {@link PredictionContextCache} object that makes sure that all
+ * {@link PredictionContext} objects are shared among the DFA states. This makes
+ * a big size difference.</p>
+ *
+ * <p>
+ * <strong>THREAD SAFETY</strong></p>
+ *
+ * <p>
+ * The {@link ParserATNSimulator} locks on the {@link #decisionToDFA} field when
+ * it adds a new DFA object to that array. {@link #addDFAEdge}
+ * locks on the DFA for the current decision when setting the
+ * {@link DFAState#edges} field. {@link #addDFAState} locks on
+ * the DFA for the current decision when looking up a DFA state to see if it
+ * already exists. We must make sure that all requests to add DFA states that
+ * are equivalent result in the same shared DFA object. This is because lots of
+ * threads will be trying to update the DFA at once. The
+ * {@link #addDFAState} method also locks inside the DFA lock
+ * but this time on the shared context cache when it rebuilds the
+ * configurations' {@link PredictionContext} objects using cached
+ * subgraphs/nodes. No other locking occurs, even during DFA simulation. This is
+ * safe as long as we can guarantee that all threads referencing
+ * {@code s.edge[t]} get the same physical target {@link DFAState}, or
+ * {@code null}. Once into the DFA, the DFA simulation does not reference the
+ * {@link DFA#states} map. It follows the {@link DFAState#edges} field to new
+ * targets. The DFA simulator will either find {@link DFAState#edges} to be
+ * {@code null}, to be non-{@code null} and {@code dfa.edges[t]} null, or
+ * {@code dfa.edges[t]} to be non-null. The
+ * {@link #addDFAEdge} method could be racing to set the field
+ * but in either case the DFA simulator works; if {@code null}, and requests ATN
+ * simulation. It could also race trying to get {@code dfa.edges[t]}, but either
+ * way it will work because it's not doing a test and set operation.</p>
+ *
+ * <p>
+ * <strong>Starting with SLL then failing to combined SLL/LL (Two-Stage
+ * Parsing)</strong></p>
+ *
+ * <p>
+ * Sam pointed out that if SLL does not give a syntax error, then there is no
+ * point in doing full LL, which is slower. We only have to try LL if we get a
+ * syntax error. For maximum speed, Sam starts the parser set to pure SLL
+ * mode with the {@link BailErrorStrategy}:</p>
+ *
+ * <pre>
+ * parser.{@link Parser#getInterpreter() getInterpreter()}.{@link #setPredictionMode setPredictionMode}{@code (}{@link PredictionMode#SLL}{@code )};
+ * parser.{@link Parser#setErrorHandler setErrorHandler}(new {@link BailErrorStrategy}());
+ * </pre>
+ *
+ * <p>
+ * If it does not get a syntax error, then we're done. If it does get a syntax
+ * error, we need to retry with the combined SLL/LL strategy.</p>
+ *
+ * <p>
+ * The reason this works is as follows. If there are no SLL conflicts, then the
+ * grammar is SLL (at least for that input set). If there is an SLL conflict,
+ * the full LL analysis must yield a set of viable alternatives which is a
+ * subset of the alternatives reported by SLL. If the LL set is a singleton,
+ * then the grammar is LL but not SLL. If the LL set is the same size as the SLL
+ * set, the decision is SLL. If the LL set has size &gt; 1, then that decision
+ * is truly ambiguous on the current input. If the LL set is smaller, then the
+ * SLL conflict resolution might choose an alternative that the full LL would
+ * rule out as a possibility based upon better context information. If that's
+ * the case, then the SLL parse will definitely get an error because the full LL
+ * analysis says it's not viable. If SLL conflict resolution chooses an
+ * alternative within the LL set, them both SLL and LL would choose the same
+ * alternative because they both choose the minimum of multiple conflicting
+ * alternatives.</p>
+ *
+ * <p>
+ * Let's say we have a set of SLL conflicting alternatives {@code {1, 2, 3}} and
+ * a smaller LL set called <em>s</em>. If <em>s</em> is {@code {2, 3}}, then SLL
+ * parsing will get an error because SLL will pursue alternative 1. If
+ * <em>s</em> is {@code {1, 2}} or {@code {1, 3}} then both SLL and LL will
+ * choose the same alternative because alternative one is the minimum of either
+ * set. If <em>s</em> is {@code {2}} or {@code {3}} then SLL will get a syntax
+ * error. If <em>s</em> is {@code {1}} then SLL will succeed.</p>
+ *
+ * <p>
+ * Of course, if the input is invalid, then we will get an error for sure in
+ * both SLL and LL parsing. Erroneous input will therefore require 2 passes over
+ * the input.</p>

+ * during closure operations. See antlr/antlr4#1398.
+ *
+ * The optimization is to avoid adding the loop entry config when
+ * the exit path can only lead back to the same
+ * StarLoopEntryState after popping context at the rule end state
+ * (traversing only epsilon edges, so we're still in closure, in
+ * this same rule).
+ *
+ * We need to detect any state that can reach loop entry on
+ * epsilon w/o exiting rule. We don't have to look at FOLLOW
+ * links, just ensure that all stack tops for config refer to key
+ * states in LR rule.
+ *
+ * To verify we are in the right situation we must first check
+ * closure is at a StarLoopEntryState generated during LR removal.
+ * Then we check that each stack top of context is a return state
+ * from one of these cases:
+ *
+ * 1. 'not' expr, '(' type ')' expr. The return state points at loop entry state
+ * 2. expr op expr. The return state is the block end of internal block of (...)*
+ * 3. 'between' expr 'and' expr. The return state of 2nd expr reference.
+ * That state points at block end of internal block of (...)*.
+ * 4. expr '?' expr ':' expr. The return state points at block end,
+ * which points at loop entry state.
+ *
+ * If any is true for each stack top, then closure does not add a
+ * config to the current config set for edge[0], the loop entry branch.
+ *
+ * Conditions fail if any context for the current config is:
+ *
+ * a. empty (we'd fall out of expr to do a global FOLLOW which could
+ * even be to some weird spot in expr) or,
+ * b. lies outside of expr or,
+ * c. lies within expr but at a state not the BlockEndState
+ * generated during LR removal
+ *
+ * Do we need to evaluate predicates ever in closure for this case?
+ *
+ * No. Predicates, including precedence predicates, are only
+ * evaluated when computing a DFA start state. I.e., only before
+ * the lookahead (but not parser) consumes a token.
+ *
+ * There are no epsilon edges allowed in LR rule alt blocks or in
+ * the "primary" part (ID here). If closure is in
+ * StarLoopEntryState any lookahead operation will have consumed a
+ * token as there are no epsilon-paths that lead to
+ * StarLoopEntryState. We do not have to evaluate predicates
+ * therefore if we are in the generated StarLoopEntryState of a LR
+ * rule. Note that when making a prediction starting at that
+ * decision point, decision d=2, compute-start-state performs
+ * closure starting at edges[0], edges[1] emanating from
+ * StarLoopEntryState. That means it is not performing closure on
+ * StarLoopEntryState during compute-start-state.
+ *
+ * How do we know this always gives same prediction answer?
+ *
+ * Without predicates, loop entry and exit paths are ambiguous
+ * upon remaining input +b (in, say, a+b). Either paths lead to
+ * valid parses. Closure can lead to consuming + immediately or by
+ * falling out of this call to expr back into expr and loop back
+ * again to StarLoopEntryState to match +b. In this special case,
+ * we choose the more efficient path, which is to take the bypass
+ * path.
+ *
+ * The lookahead language has not changed because closure chooses
+ * one path over the other. Both paths lead to consuming the same
+ * remaining input during a lookahead operation. If the next token
+ * is an operator, lookahead will enter the choice block with
+ * operators. If it is not, lookahead will exit expr. Same as if
+ * closure had chosen to enter the choice block immediately.
+ *
+ * Closure is examining one config (some loopentrystate, some alt,
+ * context) which means it is considering exactly one alt. Closure
+ * always copies the same alt to any derived configs.
+ *
+ * How do we know this optimization doesn't mess up precedence in
+ * our parse trees?
+ *
+ * Looking through expr from left edge of stat only has to confirm
+ * that an input, say, a+b+c; begins with any valid interpretation
+ * of an expression. The precedence actually doesn't matter when
+ * making a decision in stat seeing through expr. It is only when
+ * parsing rule expr that we must use the precedence to get the
+ * right interpretation and, hence, parse tree.

+
+ applyPrecedenceFilter is an optimization to avoid highly
+ nonlinear prediction of expressions and other left recursive
+ rules. The precedence predicates such as {3>=prec}? Are highly
+ context-sensitive in that they can only be properly evaluated
+ in the context of the proper prec argument. Without pruning,
+ these predicates are normal predicates evaluated when we reach
+ conflict state (or unique prediction). As we cannot evaluate
+ these predicates out of context, the resulting conflict leads
+ to full LL evaluation and nonlinear prediction which shows up
+ very clearly with fairly large expressions.
+
+ Example grammar:
+
+ e : e '*' e
+ | e '+' e
+ | INT
+ ;
+
+ We convert that to the following:
+
+ e[int prec]
+ : INT
+ ( {3>=prec}? '*' e[4]
+ | {2>=prec}? '+' e[3]
+ )*
+ ;
+
+ The (..)* loop has a decision for the inner block as well as
+ an enter or exit decision, which is what concerns us here. At
+ the 1st + of input 1+2+3, the loop entry sees both predicates
+ and the loop exit also sees both predicates by falling off the
+ edge of e. This is because we have no stack information with
+ SLL and find the follow of e, which will hit the return states
+ inside the loop after e[4] and e[3], which brings it back to
+ the enter or exit decision. In this case, we know that we
+ cannot evaluate those predicates because we have fallen off
+ the edge of the stack and will in general not know which prec
+ parameter is the right one to use in the predicate.
+
+ Because we have special information, that these are precedence
+ predicates, we can resolve them without failing over to full
+ LL despite their context sensitive nature. We make an
+ assumption that prec[-1] <= prec[0], meaning that the current
+ precedence level is greater than or equal to the precedence
+ level of recursive invocations above us in the stack. For
+ example, if predicate {3>=prec}? is true of the current prec,
+ then one option is to enter the loop to match it now. The
+ other option is to exit the loop and the left recursive rule
+ to match the current operator in rule invocation further up
+ the stack. But, we know that all of those prec are lower or
+ the same value and so we can decide to enter the loop instead
+ of matching it later. That means we can strip out the other
+ configuration for the exit branch.
+
+ So imagine we have (14,1,$,{2>=prec}?) and then
+ (14,2,$-dipsIntoOuterContext,{2>=prec}?). The optimization
+ allows us to collapse these two configurations. We know that
+ if {2>=prec}? is true for the current prec parameter, it will
+ also be true for any prec from an invoking e call, indicated
+ by dipsIntoOuterContext. As the predicates are both true, we
+ have the option to evaluate them early in the decision start
+ state. We do this by stripping both predicates and choosing to
+ enter the loop as it is consistent with the notion of operator
+ precedence. It's also how the full LL conflict resolution
+ would work.
+
+ The solution requires a different DFA start state for each
+ precedence level.
+
+ The basic filter mechanism is to remove configurations of the
+ form (p, 2, pi) if (p, 1, pi) exists for the same p and pi. In
+ other words, for the same ATN state and predicate context,
+ remove any configuration associated with an exit branch if
+ there is a configuration associated with the enter branch.
+
+ It's also the case that the filter evaluates precedence
+ predicates and resolves conflicts according to precedence
+ levels. For example, for input 1+2+3 at the first +, we see
+ prediction filtering
+
+ [(11,1,[$],{3>=prec}?), (14,1,[$],{2>=prec}?), (5,2,[$],up=1),
+ (11,2,[$],up=1), (14,2,[$],up=1)],hasSemanticContext=true,dipsIntoOuterContext
+
+ to
+
+ [(11,1,[$]), (14,1,[$]), (5,2,[$],up=1)],dipsIntoOuterContext
+
+ This filters because {3>=prec}? evals to true and collapses
+ (11,1,[$],{3>=prec}?) and (11,2,[$],up=1) since early conflict
+ resolution based upon rules of operator precedence fits with
+ our usual match first alt upon conflict.
+
+ We noticed a problem where a recursive call resets precedence
+ to 0. Sam's fix: each config has flag indicating if it has
+ returned from an expr[0] call. then just don't filter any
+ config with that flag set. flag is carried along in
+ closure(). so to avoid adding field, set bit just under sign
+ bit of dipsIntoOuterContext (SUPPRESS_PRECEDENCE_FILTER).
+ With the change you filter "unless (p, 2, pi) was reached
+ after leaving the rule stop state of the LR rule containing
+ state p, corresponding to a rule invocation with precedence
+ level 0"

+ * <li>The closure block cannot contain any epsilon transitions which bypass

+ * <li>The "primary" portion of a left recursive rule cannot contain an

+ * to the left-recursive rule, with the outer calls not being at the

+ * {@link ATNConfig#isPrecedenceFilterSuppressed} property marks ATN

+ * State 8 is the state right before B. Clearly alternatives 1 and 2
+ * conflict and no amount of further lookahead will separate the two.
+ * However, alternative 3 will be able to continue and so we do not stop
+ * working on this state. In the previous example, we're concerned with
+ * states associated with the conflicting alternatives. Here alt 3 is not
+ * associated with the conflicting configs, but since we can continue
+ * looking for input reasonably, don't declare the state done.</p>
+ *
+ * <p><strong>PURE SLL PARSING</strong></p>
+ *
+ * <p>To handle pure SLL parsing, all we have to do is make sure that we
+ * combine stack contexts for configurations that differ only by semantic
+ * predicate. From there, we can do the usual SLL termination heuristic.</p>
+ *
+ * <p><strong>PREDICATES IN SLL+LL PARSING</strong></p>
+ *
+ * <p>SLL decisions don't evaluate predicates until after they reach DFA stop
+ * states because they need to create the DFA cache that works in all
+ * semantic situations. In contrast, full LL evaluates predicates collected
+ * during start state computation so it can ignore predicates thereafter.
+ * This means that SLL termination detection can totally ignore semantic
+ * predicates.</p>
+ *
+ * <p>Implementation-wise, {@link ATNConfigSet} combines stack contexts but not
+ * semantic predicate contexts so we might see two configurations like the
+ * following.</p>
+ *
+ * <p>{@code (s, 1, x, {}), (s, 1, x', {p})}</p>
+ *
+ * <p>Before testing these configurations against others, we have to merge
+ * {@code x} and {@code x'} (without modifying the existing configurations).
+ * For example, we test {@code (x+x')==x''} when looking for conflicts in
+ * the following configurations.</p>
+ *
+ * <p>{@code (s, 1, x, {}), (s, 1, x', {p}), (s, 2, x'', {})}</p>
+ *
+ * <p>If the configuration set has predicates (as indicated by
+ * {@link ATNConfigSet#hasSemanticContext}), this algorithm makes a copy of
+ * the configurations to strip out all of the predicates so that a standard
+ * {@link ATNConfigSet} will merge everything ignoring predicates.</p>

+ * Full LL prediction termination.
+ *
+ * <p>Can we stop looking ahead during ATN simulation or is there some
+ * uncertainty as to which alternative we will ultimately pick, after
+ * consuming more input? Even if there are partial conflicts, we might know
+ * that everything is going to resolve to the same minimum alternative. That
+ * means we can stop since no more lookahead will change that fact. On the
+ * other hand, there might be multiple conflicts that resolve to different
+ * minimums. That means we need more look ahead to decide which of those
+ * alternatives we should predict.</p>
+ *
+ * <p>The basic idea is to split the set of configurations {@code C}, into
+ * conflicting subsets {@code (s, _, ctx, _)} and singleton subsets with
+ * non-conflicting configurations. Two configurations conflict if they have
+ * identical {@link ATNConfig#state} and {@link ATNConfig#context} values
+ * but different {@link ATNConfig#alt} value, e.g. {@code (s, i, ctx, _)}
+ * and {@code (s, j, ctx, _)} for {@code i!=j}.</p>
+ *
+ * <p>Reduce these configuration subsets to the set of possible alternatives.
+ * You can compute the alternative subsets in one pass as follows:</p>
+ *
+ * <p>{@code A_s,ctx = {i | (s, i, ctx, _)}} for each configuration in
+ * {@code C} holding {@code s} and {@code ctx} fixed.</p>
+ *
+ * <p>Or in pseudo-code, for each configuration {@code c} in {@code C}:</p>
+ *
+ * <pre>
+ * map[c] U= c.{@link ATNConfig#alt alt} # map hash/equals uses s and x, not
+ * alt and not pred
+ * </pre>
+ *
+ * <p>The values in {@code map} are the set of {@code A_s,ctx} sets.</p>
+ *
+ * <p>If {@code |A_s,ctx|=1} then there is no conflict associated with
+ * {@code s} and {@code ctx}.</p>
+ *
+ * <p>Reduce the subsets to singletons by choosing a minimum of each subset. If
+ * the union of these alternative subsets is a singleton, then no amount of
+ * more lookahead will help us. We will always pick that alternative. If,
+ * however, there is more than one alternative, then we are uncertain which
+ * alternative to predict and must continue looking for resolution. We may
+ * or may not discover an ambiguity in the future, even if there are no
+ * conflicting subsets this round.</p>
+ *
+ * <p>The biggest sin is to terminate early because it means we've made a
+ * decision but were uncertain as to the eventual outcome. We haven't used
+ * enough lookahead. On the other hand, announcing a conflict too late is no
+ * big deal; you will still have the conflict. It's just inefficient. It
+ * might even look until the end of file.</p>
+ *
+ * <p>No special consideration for semantic predicates is required because
+ * predicates are evaluated on-the-fly for full LL prediction, ensuring that
+ * no configuration contains a semantic context during the termination
+ * check.</p>
+ *
+ * <p><strong>CONFLICTING CONFIGS</strong></p>
+ *
+ * <p>Two configurations {@code (s, i, x)} and {@code (s, j, x')}, conflict
+ * when {@code i!=j} but {@code x=x'}. Because we merge all
+ * {@code (s, i, _)} configurations together, that means that there are at
+ * most {@code n} configurations associated with state {@code s} for
+ * {@code n} possible alternatives in the decision. The merged stacks
+ * complicate the comparison of configuration contexts {@code x} and
+ * {@code x'}. Sam checks to see if one is a subset of the other by calling
+ * merge and checking to see if the merged result is either {@code x} or
+ * {@code x'}. If the {@code x} associated with lowest alternative {@code i}
+ * is the superset, then {@code i} is the only possible prediction since the
+ * others resolve to {@code min(i)} as well. However, if {@code x} is
+ * associated with {@code j>i} then at least one stack configuration for
+ * {@code j} is not in conflict with alternative {@code i}. The algorithm
+ * should keep going, looking for more lookahead due to the uncertainty.</p>
+ *
+ * <p>For simplicity, I'm doing a equality check between {@code x} and
+ * {@code x'} that lets the algorithm continue to consume lookahead longer
+ * than necessary. The reason I like the equality is of course the
+ * simplicity but also because that is the test you need to detect the
+ * alternatives that are actually in conflict.</p>
+ *
+ * <p><strong>CONTINUE/STOP RULE</strong></p>
+ *
+ * <p>Continue if union of resolved alternative sets from non-conflicting and
+ * conflicting alternative subsets has more than one alternative. We are
+ * uncertain about which alternative to predict.</p>
+ *
+ * <p>The complete set of alternatives, {@code [i for (_,i,_)]}, tells us which
+ * alternatives are still in the running for the amount of input we've
+ * consumed at this point. The conflicting sets let us to strip away
+ * configurations that won't lead to more states because we resolve
+ * conflicts to the configuration with a minimum alternate for the
+ * conflicting set.</p>
+ *
+ * <p><strong>CASES</strong></p>
+ *
+ * <ul>
+ *
+ * <li>no conflicts and more than 1 alternative in set =&gt; continue</li>
+ *
+ * <li> {@code (s, 1, x)}, {@code (s, 2, x)}, {@code (s, 3, z)},

+ *

+ * {@code {1}} = {@code {1}} =&gt; stop and predict 1, can announce
+ * ambiguity {@code {1,2}}</li>
+ *
+ * <li>{@code (s, 1, x)}, {@code (s, 2, x)}, {@code (s', 2, y)},
+ * {@code (s', 3, y)} yields conflicting, reduced sets {@code {1}} U

+ * {@code (s', 4, y)} yields conflicting, reduced sets {@code {1}} U
+ * {@code {3}} = {@code {1,3}} =&gt; continue</li>
+ *
+ * </ul>
+ *
+ * <p><strong>EXACT AMBIGUITY DETECTION</strong></p>
+ *
+ * <p>If all states report the same conflicting set of alternatives, then we
+ * know we have the exact ambiguity set.</p>
+ *
+ * <p><code>|A_<em>i</em>|&gt;1</code> and
+ * <code>A_<em>i</em> = A_<em>j</em></code> for all <em>i</em>, <em>j</em>.</p>
+ *
+ * <p>In other words, we continue examining lookahead until all {@code A_i}
+ * have more than one alternative and all {@code A_i} are the same. If
+ * {@code A={{1,2}, {1,3}}}, then regular LL prediction would terminate
+ * because the resolved set is {@code {1}}. To determine what the real
+ * ambiguity is, we have to know whether the ambiguity is between one and
+ * two or one and three so we keep going. We can only stop prediction when
+ * we need exact ambiguity detection when the sets look like
