This can be done as follows: There are two elements which can be on the stack, p and q. The stack begins as empty. When the automaton reads a b, it either removes a q, if a q is on the top of the stack, or pushes a p otherwise. When the automaton reads an a or c, it either removes a p, if a p is on the top of the stack, or pushes a q …

WebMar 17, 2024 · Sometimes the stack can actually help. For example, PDAs are very good at counting things. Consider the problem of designing an automaton to recognize strings with k occurrences of 101, where k is some constant. Consider the language of strings over 0, 1 that contain exactly three non-overlapping occurrences of 101. WebPushdown automata is a way to implement a CFG in the same way we design DFA for a regular grammar. A DFA can remember a finite amount of information, but a PDA can remember an infinite amount of information. …

WebThe text then goes on to give a detailed description of context-free languages, pushdown automata and computability of Turing machine, with its complexity and recursive features. The book concludes by giving clear insights into the theory of computability and computational complexity.
