WebFeb 25, 2024 · Pushdown Automata Question 4 Detailed Solution The correct answer is option 1 and option 4. Concept: The given language is, {anbn n≥1, n≠100} It accepts the strings like= {ab, aabb, aaabbb, aaaabbbb,...} The given language is Deterministic context-free language. {a n b n n≥1,n≠100} a n b n n≥1 is CFL and in particular is a DCFL.

automata - Deterministic vs. Non-Deterministic PDA?

WebPushdown Automata The PDA is an automaton equivalent to the CFG in language-defining power. Only the nondeterministic PDA defines all the CFL’s. But the deterministic version models parsers. Most programming languages have deterministic PDA’s. Web6.Deterministic Pushdown Automata § Definition: A PDA M = ( Q, Σ, Γ, δ, q 0, z, F) is deterministic if for every q ∈ Q, a ∈ Σ ∪ { λ } , b ∈ Γ: 1. δ ( q, a, b) contains at most one element 2. if δ ( q, λ, b) is not empty, then δ ( q, c, b) must be empty for every c ∈ Σ. cufflinks uae https://thephonesclub.com
