✦ Synopsis


We extend results due to Blfizsik et al. (1993) on graphs with no induced C4 and 2K2 to the self-complementary class of (P5, Ps)-free graphs. Moreover, we obtain an O(eJ 2) x-binding function for this last class of graphs, answering thus partially a question of A. Gyfirf~s.

We use the modular decomposition to give O(n(m + n)) algorithms for finding a maximum weighted clique (respectively stable set) and an approximate weighted colouring (respectively partition into cliques) in a (&,E)-free graph. As a by-product, we obtain an O(m+n) algorithm for finding a minimum weig
