(English Abstract)
Given two strings x and y of the same length, when all ranks of characters in x and y are the same, x is order-isomorphic to y . Given a text T and a pattern set P consisting of k patterns, order-preserving multiple pattern matching problem is to find all substrings in T that are order-isomorphic to any pattern in P. In this paper, when the size of a q-gram is q and the sum of lengths of patterns is M, we propose a space-efficient hashing-based algorithm for order-preserving multiple pattern matching problem to reduce space complexity from O (q! k M)to O(k M)
