locality of formal grammars

... possible grammars having at most k of these rules. Since each k-simple component of 0 has at most k rules, the generated set of grammars will include all of the k-simple components of G. Step ... 3.1 Let D(G) denote the set of all deriva. tion trees of G, and let r E I)(G). Then, the degree of locality of r, written locality( r), is defined as follows, locality( r) card{ (p,q, n) I ... place.
