A Computer Science portal for geeks. If 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. Purpose of the Theory of Computation: Develop formal math-ematical models of computation that reflect real-world computers. Now if you observe you’ll find out Q X Σ –> Q is part of Q X Σ –> 2 Q..
