Method Detail

findSeparatingWord

public Word<I> findSeparatingWord(DFA<?,I> target,
                         Collection<? extends I> inputs,
                         boolean omitUndefined)

Description copied from interface: IncrementalConstruction

Checks the current state of the construction against a given target model, and returns a word exposing a difference if there is one.

Parameters:

target - the target automaton model

inputs - the set of input symbols to consider

omitUndefined - if this is set to true, then undefined transitions in the target model will be interpreted as "unspecified/don't know" and omitted in the equivalence test. Otherwise, they will be interpreted in the usual manner (e.g., non-accepting sink in case of DFAs).

Returns:

a separating word, or null if no difference could be found.

getState

replaceOrRegister

protected net.automatalib.incremental.dfa.dag.State replaceOrRegister(net.automatalib.incremental.dfa.dag.StateSignature sig)

Returns (and possibly creates) the canonical state for the given signature.

Parameters:

sig - the signature

Returns:

the canonical state for the given signature

replaceOrRegister

protected net.automatalib.incremental.dfa.dag.State replaceOrRegister(net.automatalib.incremental.dfa.dag.State state)

Returns the canonical state for the given state's signature, or registers the state as canonical if no state with that signature exists.

Parameters:

state - the state

Returns:

the canonical state for the given state's signature
