Nested word — In computer science, more specifically in automata and formal language theory, nested words are a concept proposed by Alur and Madhusudan as a joint generalization of words, as traditionally used for modelling linearly ordered structures, and of… … Wikipedia
Deterministic pushdown automaton — In automata theory, a pushdown automaton is a finite automaton with an additional stack of symbols; its transitions can take the top symbol on the stack and depend on its value, and they can add new top symbols to the stack. A deterministic… … Wikipedia
Deterministic automaton — is a concept of automata theory in which the outcome of a transition from one state to another given a certain input can be predicted for every occurrence. A common deterministic automaton is a deterministic finite state machine (sometimes… … Wikipedia

Context-free grammar — In formal language theory, a context free grammar (CFG) is a formal grammar in which every production rule is of the form V → w where V is a single nonterminal symbol, and w is a string of terminals and/or nonterminals (w can be empty). The… … Wikipedia
