PDAsPushdownAutomataare simplyNFAsaugmented with external stack memory.PDAPushdown automatacan manage memory last-in-first-out with the addition of stacks. An infinite amount of information can be stored in pushdown automata. The stack can be accessed in a limited manner. An element can be pushed...
A finite state machine does not employ any stack and only bothers about the input signal and the current state that does not work in the case of context free grammar.Push Down Automatais different from finite state machine because, It uses top of the stack for deciding which transition is ...
In the following sections, we consider L given by pushdown, visibly pushdown automata and by Ltl, CaRet or Nwtl formulas. 3. Pushdown specification Pushdown modular games. A pushdown modular game is a pair 〈G,P〉 where G is an RGG and P is a pushdown automaton, whose accepted language...
