The following problem is investigated. Let L be a given finite language, L⊂Ln = ab: 1≤a,b≤n, a≠b. 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(n2/log n) is proved, and languages satisfying c(L) = ¦L¦are characterized
It is well-known that context-free languages defined over a one-letter alpha-bet are regular. This i...
