A practical method is presented for the automatic generation of a non-recursive context-free grammar (cfg) from a set of strings that the cfg is required to be capable of producing. The method is efficient in computing time by comparison with enumerative methods.
A new dynamical measure of the descriptional complexity for context-free grammars and languages, namely the degree of cooperation, is introduced and studied. This measure is connected with respect to both families of languages considered, namely the regular and context-free languages. We prove that
