Abstract

An efficiently total dominating set of a graph G is a subset of its vertices such that each vertex of G is adjacent to exactly one vertex of the subset. If there is such a subset, then G is an efficiently total dominatable graph (G is etd). We show that the corresponding etd decision problem is NP-complete on (1,2)-colorable chordal graphs and on planar bipartite graphs of maximum degree 3 and obtain polynomial solvability on T_3-free chordal graphs, implying polynomial solvability on interval graphs and circular arc graphs.
