WebNov 5, 2015 · One way of determining whether a given context-free grammar G produces an infinite language is this: Find a grammar G + with L ( G +) = L ( G) such that G ′ has no rules on the form A → ε or A → B where A and B are any non-terminals. (Implication: for any derivation α A _ β ⇒ α γ β we have α A β < α γ β unless γ is a single terminal.) Webcontext.

WebAug 18, 2010 · A grammar is context-free if left-hand sides of all productions contain exactly one non-terminal symbol. By definition, if one exists, then the language is context-free. An equivalent construct would be a pushdown automaton. It's the same as DFA, but with a stack available. It may be easier to build than a grammar.
