We study the problem of transforming one list (vertex) coloring of a graph into another list coloring by changing only one vertex color assignment at a time, while at all times maintaining a list coloring, given a list of allowed colors for each vertex. This problem is known to be PSPACE-complete for bipartite planar graphs. In this paper, we give precise analyses of the problem with respect to pathwidth. We first show that the problem remains PSPACE-complete even for graphs with pathwidth two. In contrast, we then give a polynomial-time algorithm to solve the problem for graphs with pathwidth one. |
