In this paper, we consider two tradeo results regarding the economy of description in parsing. One result is on the tradeo between the size of a parser and its ability to detect an error early. The other result is on the tradeo between the size of an LR(k)-grammar and the length k of the lookahead.

We give an exponential upper bound in p 4 on the size of any obstruction for path-width at most p. We give a doubly exponential upper bound in k 5 on the size of any obstruction for tree-width at most k. We also give an upper bound on the size of any intertwine of two given trees T and T $.

Let D = {B1 , B2 , . . . , B b } be a finite family of k-subsets (called blocks) of a vset X(v) = {1, 2, . . . , v} (with elements called points). Then D is a (v, k, t) covering design or covering if every t-subset of X(v) is contained in at least one block of D. The number of blocks, b, is the size
