In linguistics and computer science, a context-free grammar (CFG) is a formal grammar in which every production rule is of the form Input your context-free grammar (CFG) here. The start symbol has already been filled in for you. The left-hand nonterminal of each production must be filled in. [ ε ] - An empty text field corresponds to epsilon. [ |] - For "or", use the standard pipe character that you use while coding.

A) push-down automata B) 2-way linear bounded automata C) both (a) and (b) D) none of these. Answer is: both (a) and (b) Explanation: Image: Related Theoretical Computer Science Stack Exchange is a question and answer site for theoretical computer scientists and researchers in related fields. It only takes a minute to … 2017-03-20 Theoretical Computer Science Stack Exchange is a question and answer site for theoretical computer scientists and researchers in related fields. the straightforward way to decide whether the language it accepts is empty is to convert the PDA into a CFG and then use the known algorithm to decide emptiness of the corresponding CFG. About Q2: A regular grammar is a "one-sided linear" context-free grammar, where at most one nonterminal appears in any rule right-part, and where that nonterminal is at the last (in right linear grammars) or first (in left linear grammars) position. Such grammars are easily translated into equivalent finite-state automata (roughly by considering each nonterminal as a state), which are Recall the CFG G4 that we gave in Example 2.4. For convenience, let's rename its variables with single letters as follows. Give parse trees and derivations for each string.

However, I can't seem to figure out how to represent this as a context free grammar, which is obviously possible since PDA == CFG. computer-science context-free-grammar. From the PDA diagram we get the transition function as follows: δ(q, a, Z0) = (q, ZZ0) δ(q, a, Z) = (q, ZZ) δ(q, ϵ, Z) = (r, Z) δ(r, b, Z) = (r, ϵ) δ(r, ϵ, Z) = (p, ϵ) δ(p, ϵ, Z) = (p, ϵ) δ(p, ϵ, Z0) = (p, ϵ) Now let G be the context free grammar and V be the set of variables.

Reset Example Abstract. Stochastic context-free grammars (SCFGs) have been used in RNA secondary structure modeling. An SCFG consists of a set of grammar rules with a probability for each rule. Given a grammar design, finding the best set of probabilities that yield optimum performance can be challenging.
