On the parameterized complexity of b-chromatic number

作者:

Highlights:

• We show that b-Chromatic Number is W[1]-hard when parameterized by the b-chromatic number, k.

• When k=Δ(G)+1, an algorithm of running in 2O(k2log⁡k)nO(1) is provided.

• An O(3nn4log⁡n) time algorithm on an n-vertex graph is provided.
