Maximal Independent Sets in Generalised Caterpillar Graphs
A caterpillar graph is a tree which on removal of all its pendant vertices
leaves a chordless path. The chordless path is called the backbone of the
graph. The edges from the backbone to the pendant vertices are called the hairs
of the caterpillar graph. Ortiz and Villanueva (C.Ortiz and M.Villanueva,
Discrete Applied Mathematics, 160(3): 259-266, 2012) describe an algorithm,
linear in the size of the output, for finding a family of maximal independent
sets in a caterpillar graph.
In this paper, we propose an algorithm, again linear in the output size, for
a generalised caterpillar graph, where at each vertex of the backbone, there
can be any number of hairs of length one and at most one hair of length two
