Reconfiguration of Steiner Trees in an Unweighted Graph

Conference paper
Part of the Lecture Notes in Computer Science book series (LNCS, volume 9843)


We study a reconfiguration problem for Steiner trees in an unweighted graph, which determines whether there exists a sequence of Steiner trees that transforms a given Steiner tree into another one by exchanging a single edge at a time. In this paper, we show that the problem is PSPACE-complete even for split graphs (and hence for chordal graphs), while solvable in linear time for interval graphs.
