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. WebThe non-deterministic pushdown automata is very much similar to NFA. We will discuss some CFGs which accepts NPDA. The CFG which accepts deterministic PDA accepts non-deterministic PDAs as well. Similarly, there are some CFGs which can be accepted only by NPDA and not by DPDA. Thus NPDA is more powerful than DPDA. Example:

Let M be a DFA. 1. Since all DFA’s are PDA’s, M is a PDA. For all PDA’s M there exists CFL G such that L(M) = L(G). The drawback of this proof is that it requires PDA-to-CFG theorem. 2. Web2 Answers. The set of all regular languages is a subset of context free languages. So if you have a context free grammar (CFG) that generates a regular languages, you most certainly can convert it to a regular expression (RE), regular grammar (RG), or finite automata (FA).
