Abstract

We present an approximation algorithm for the problem of finding a minimum set of edges in a given graph G whose removal from G leaves a graph in which each connected component is a path It achieves a ratio of frac 107 and runs in On 15 time where n is the number of vertices in the input graph The previously best approximation algorithm for this problem achieves a ratio of 2 and runs in On 2 time
