WebIn graph theory, a clique cover or partition into cliques of a given undirected graph is a partition of the vertices into cliques, subsets of vertices within which every two vertices are adjacent.A minimum clique cover is a clique cover that uses as few cliques as possible. The minimum k for which a clique cover exists is called the clique cover number of the … WebM. R. Garey and D. S. Johnson, Computers and Intractibility: a guide to the theory of NP-completeness, W.H.
