Abstract

For an integer d1d\geq 1, the dd-Cut problem is that of deciding whether a graph has an edge cut in which each vertex is adjacent to at most dd vertices on the opposite side of the cut. The 11-Cut problem is the well-known Matching Cut problem. The dd-Cut problem has been extensively studied for HH-free graphs. We extend these results to the probe graph model, where we do not know all the edges of the input graph. For a graph HH, a partitioned probe HH-free graph (G,P,N)(G,P,N) consists of a graph G=(V,E)G=(V,E), together with a set PVP\subseteq V of probes and an independent set N=VPN=V\setminus P of non-probes such that we can change GG into an HH-free graph by adding zero or more edges between vertices in NN. For every graph HH and every integer d1d\geq 1, we completely determine the complexity of dd-Cut on partitioned probe HH-free graphs.
