Abstract(in English) Alignment based on DP-matching is used to extract unknown feature pattern embedded in genome sequence. To extract feature pattern with base length n, complete set of similarity of candidate pattern with base length N=2, 3, …, n is required. When extending base length n, number of candidate pattern and execution time increase exponential order O(4^). This paper propose a new faster method of extracting feature pattern by reusing similartiy which is calculated past step. The method enable extracting feature pattern with base length n=10 to speed up as much as 9 times than conventional method.
