It is possible to define the term simplification precisely by introducing the concept of complexity of a grammar. This can be done in many ways; one of them is through the length of all the strings giving the production rules. For example, we might use: complerin@ =v.d I +lv). A context-free grammar Gmin is said to be minimal for a given language L if L(Gmin)L and complexity Gnn) complexity(G) for any G such that L(G L Does a removal of useless symbols always produce a minimal grammar?
