一种少重最小公共串划分的固定参数算法

A Fixed-Parameter Algorithm for Minimum Common String Partition with Few Duplications

Laurent Bulteau, Guillaume Fertin, Christian Komusiewicz, Irena Rusu

摘要:

受基因组重排研究的启发,NP难的最小公共串划分问题要求,给定两个字符串,将两个字符串分成一组相同的块。我们考虑这个问题的扩展到不平衡的字符串,使一些元素可能不会被任何块覆盖。我们提出了一个有效的固定参数算法的参数数k的块和最大出现d的一个字母在任一字符串。然后,我们评估该算法的细菌基因组和合成数据。

英文摘要:

Motivated by the study of genome rearrangements, the NP-hard Minimum Common String Partition problems asks, given two strings, to split both strings into an identical set of blocks. We consider an extension of this problem to unbalanced strings, so that some elements may not be covered by any block. We present an efficient fixed-parameter algorithm for the parameters number k of blocks and maximum occurrence d of a letter in either string. We then evaluate this algorithm on bacteria genomes and synthetic data.
