For a graph G and its vertex subset S , a vertex v ∈ S is happy if all v's neighbors in G are contained in S . Given a graph G and a non-negative integer k, MAXIMUM HAPPY SET is the problem of finding a vertex subset S of G such that, In this technical report, we investigate the complexity of the MAXIMUM HAPPY SET problem on subclasses of co-comparability graphs.
