In the PATHWIDTH ONE VERTEX DELETION (POVD) problem the input is a graph G and an integer k, and the goal is to decide whether there is a set of at most k vertices whose removal from G results in a graph with pathwidth at most 1. In this paper we give an algorithm for POVD whose running time is O(3.888k).
