PFA

Returns true if this automaton accepts the given string.

Calculate the probability that the automaton accepts the given sequence

Return the pairs comprising all unlabelled transitions.

Returns the probability of a transition state s0 into state s1 without a labeled event.

Return the indices of the final states.

Returns the probability that s is a final state of this automaton.

Returns the Set of final states in this automaton.

Perform some action for each epsilon transition in the automaton. Note that in many (deterministic) automata, this method is a no-op, but in included for an easy consistency.

Perform some action for each final state in the automaton.

Perform some action for each final state in the automaton.

Perform some action for each initial state in the automaton.

Perform some action for each initial state in the automaton.

Perform some action for each state in the automaton.

Perform some action for each state in the automaton.

Perform some action for each transition in the automaton.

Perform some action for each transition in the automaton.

Return the index of a state, or None.

Return the index of a label, or None.

Use Graphviz to render this object as specified.

Use Graphviz to render this object (in the default format) to the given file.

Return the index of a state. Since this is a Map, a call on a value which is not a state will throw an exception; use getIndexOf for a safe version.

Returns the probability that s is an initial state of this automaton.

Returns the Set of initial states in this automaton.

Returns true if s has a non-zero chance of being a final state of the automaton

Returns whether the given state s is initial in this automaton.

Returns true if s is used as a state

Label at a particular index.

Index of a particular label. Since this is a Map, a call on a value which is not a label will throw an exception; use getIndexOf for a safe version.

Derive a new isomorphic automaton from this one by applying transforms to the states and transitions. This method does not check that either map is injective: if they are not, then the result may be unpredictable.

Derive a new isomorphic automaton from this one by applying transforms to the states. This method does not check that the stateMap is injective: if it is not, then the result may have separate states which cannot be distinguished.

Returns the states into which the automaton could transition with non-zero probability starting from s via a transition labelled t.

In the resulting map, each resulting state is associated with the probability of that transition taking place.

Number of states in the automaton

Return the state at a particular index.

Return the inner lines of a digraph block (or other Graphviz style) to render this object.

Returns the probability that from state s0 and with label t, this state would transition into state s1.

Return the triples comprising all labelled transitions.

Returns the (possibly empty, and in deterministic implementations at most singleton) set of states into which the automaton could transition starting from s via a transition labelled t.
