Abstract

Given q + 1 strings (a text t of length n and q patterns m 1 , … , m q ) and a natural number w, the multiple serial episode matching problem consists in finding the number of size w windows of text t which contain patterns m 1 , … , m q as subsequences, i.e., for each m i , if m i = p 1 , … , p k , the letters p 1 , … , p k occur in the window, in the same order as in m i , but not necessarily consecutively (they may be interleaved with other letters). Our main contribution here is an algorithm solving this problem on-line in time O ( n q ) with an MP-RAM model (which is a RAM model equipped with extra operations).
