Z-함수를 이용한 순위패턴매칭과 순위다중패턴매칭 병렬계산

Abstract

Disclosed is a z-function-based parallel computation method for order-preserving pattern matching and order-preserving multiple pattern matching. Provided is a z-function-based parallel computation method, which includes a step of calculating a z-function which is a maximum length at which a prefix of a suffix CC starting at each position BB with respect to a character string AA of length n coincides with a prefix of a character string S. According to an embodiment of the present invention, it is possible to provide a parallel algorithm using a z-function, which can solve order-preserving pattern matching using DD threads for an EE time.
