Detailed Description

template<class InputSymbolTypeT = DefaultSymbolType, class PushdownStoreSymbolTypeT = DefaultSymbolType, class StateTypeT = DefaultStateType>
class automaton::DPDA< InputSymbolTypeT, PushdownStoreSymbolTypeT, StateTypeT >

Deterministic pushdown automaton. Accepts subset of context free languages.

Definition A = (Q, T, G, I, Z, \delta, F), Q (States) = nonempty finite set of states, T (TerminalAlphabet) = finite set of terminal symbols - having this empty won't let automaton do much though, G (PushdownStoreAlphabet) = finite set of pushdown store symbol - having this empty makes the automaton equivalent to DFA I (InitialState) = initial state, Z (InitialPushdownStoreSymbol) = initial pushdown store symbol \delta = transition function of the form A \times a \times \alpha -> B \times \beta, where A, B \in Q, a \in T \cup { \eps }, and \alpha, \beta \in G*, F (FinalStates) = set of final states

The transition functions must meet following criteria. Othervise adding conflicting transition will cause exception. $|\delta (q, a, \gamma)| \leq 1$, $\forall q, a, \gamma, q \in Q, a \in (T \cup \varepsilon\}), \gamma \in G^*.$ if $\delta (q, a, \alpha) \neq \emptyset$, $\delta (q, a, \beta) \neq \emptyset$ and $\alpha \neq \beta$, then $\alpha$ is not suffix of $\beta$ and $\beta$ is not suffix of $\alpha$ (formally $\gamma \alpha \neq \beta and \alpha \neq \gamma \beta$). if $\delta(q, a, \alpha) \neq \emptyset$, $\delta (q, \varepsilon, \beta) \neq \emptyset$, then $\alpha$ is not suffix of $\beta$ and $\beta$ is not suffix of $\alpha$ (fornally $\gamma \alpha \neq \beta and \alpha \neq \gamma \beta$).

Template Parameters

InputSymbolTypeT	used for the terminal alphabet
PushdownSymbolTypeT	used for the pushdown store alphabet
StateTypeT	used to the states, and the initial state of the automaton.
