Coloring perfect graphs with no balanced skew-partitions
We present an O(n) algorithm that computes a maximum stable set of any perfect graph with no balanced skew-partition. We present O(n) time algorithm that colors them.
متن کاملFinding balanced skew partitions in perfect graphs
A graph G is Berge if no induced subgraph of G is an odd cycle of length at least five or the complement of one; and it is known that this is equivalent to being perfect, that is, that the chromatic number of every induced subgraph equals the size of its largest clique. A skew partition in G is a partition (A,B) of V (G) such that G[A] is not connected and G[B] is not connected; and it is balan...
متن کاملClique-Stable Set separation in perfect graphs with no balanced skew-partitions
We prove that perfect graphs with no balanced skew-partitions admits a O(n) Clique-Stable set separator. We then prove that for every graph G in this class, there always exists two subsets of vertices V1, V2 such that |V1|, |V2| ≥ c|V (G)| for some constant c and V1 is either complete or anticomplete to V2. The method uses trigraphs, introduced by Chudnovsky [5], and relies on the good behavior...
