WebFeb 14, 2024 · Finite Automata (FA) and Push Down Automata (PDA) both are used to express the languages. The Finite Automata is deterministic and Push Down Automata is deterministic and as well as non-deterministic.

In DFA the next possible state is distinctly a set, while in NFA each pair of state and input symbol can have many possible next states.

WebPDA that recognizes the language specified by the CFG and vice versa Application: this equivalence allows a CFG to be used to specify a programming language and the equivalent PDA to be used to implement its compiler. Equivalence of Pushdown Automata with Context-Free Grammar – p.2/45 WebMar 12, 2011 · The conversions of DFA to PDA can be automated easily by just adding a stack. But there could be possible changes to the semantics of the DFA and after you change it that way manually you could end up in a PDA with less number of states. I faced this problem recently. Its somewhat like this,
WebWhile an automaton is called finite if its model consists of a finite number of states and functions with finite strings of input and output, infinite automata have an "accessory" - either a stack or a tape that can be moved to the right or left, and can meet the same demands made on a machine..

Web– In state q1 compare input symbols with the top of the stack. If match, pop the stack and proceed. If no match, then the branch of the automaton dies. – If we empty the stack then we have seen wwR and can proceed to a final accepting state.
