WebThe following steps are used to obtain PDA from CFG is: Step 1: Convert the given productions of CFG into GNF. Step 2: The PDA will only have one state {q}. Step 3: The initial symbol of CFG will be the initial symbol in the PDA. Step 4: For non-terminal symbol, add the following rule: δ (q, ε, A) = (q, α) Where the production rule is A → α WebWe then study an important subclass of GFG-PDA, namely, GFG visibly pushdown automata (VPA), in which the stack behaviour (push, pop, skip) is determined by the …

WebIf a grammar G is context-free, we can build an equivalent nondeterministic PDA which accepts the language that is produced by the context-free grammar G. A parser can be built for the grammar G. Also, if P is a pushdown automaton, an equivalent context-free grammar G can be constructed where L (G) = L (P) Webwhich otherwise require deterministic automata. Our main results are that !-GFG-PDA are more expressive than deterministic !-pushdown autom-ata and that solving in nite games with winning conditions speci ed by !-GFG-PDA is EXPTIME-complete.
