Parameterized algorithm for 3-path vertex cover

Data Structures and Algorithms 2018-09-11 v1

Abstract

In the 3-path vertex cover problem, the input is an undirected graph GG and an integer kk. The goal is to decide whether there is a set of vertices SS of size at most kk such that every path with 3 vertices in GG contains at least one vertex of SS. In this paper we give parameterized algorithm for 3-path cover whose time complexity is O(1.713k)O^*(1.713^k). Our algorithm is faster than previous algorithms for this problem.
