The following problem is investigated. Let L be a given finite language, LcL,= {ub: I ~o,bsn, of/~}. Determine the minimal natural number c(L) such that L can be generated by c(L) context-free productions. Among others, max c(L) = O(n'/log n) is proved, and languages satisfying c(L) = IL) are charac
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-
