AbstractWe prove that the weak k-linkage problem is polynomial for every fixed k for totally ï -decomposable digraphs, under appropriate hypothesis on ï . We then apply this and recent results by Fradkin and Seymour on the weak k-linkage problem for digraphs of bounded independence number or bounded cut-width to get polynomial algorithms for some classes of digraphs like quasi-transitive digraphs, extended semicomplete digraphs, locally semicomplete digraphs all of which contain the class of semicomplete digraphs as a subclass and directed cographs. |
