Molecular Aspects of Membrane Phenomena Hadwiger number of a graph is .-hard on co-bipartite graphs, but can be solved in polynomial time on cographs and on bipartite permutation graphs. We also consider a natural generalization of this problem that asks for the largest integer . such that . has a minor with . vertices and diameter at mo

We present a linear-time algorithm that solves . and finds the corresponding paths (if they exist) on circular-arc graphs. For interval graphs, we exhibit a linear-time algorithm for the generalization of . where the pai
