We prove that each context-free language possesses a test set of size \(O\left(m^{6}\right)\), where \(m\) is the number of productions in a grammar-producing the language. A context-free grammar generating the test set can be found in polynomial time by a sequential algorithm. It improves the doubl

Let A be a finite, totally ordered alphabet, and let P be the lexicographic ordering on A\*. Let X be a subset of A\*. The language of minimal words of X is the subset of X composed of the lexicographically minimal word of X for each length: The aim of this paper is to prove that if L is a context-
