Abstract |
We show how, given positive constants e and d, and an a-balanced straight-line program with g rules for a text T[1..n], we can build an O(g)-space index that, given a pattern P[1..m], in O(m log^d g) time finds with high probability a substring of P that occurs in T and whose length is at least a (1-e) fraction of the longest common substring of P and T. |
