Abstract. An independent set Ic is a critical independent set if |Ic|−|N(Ic) | ≥ |J | − |N(J)|, for any independent set J. The critical independence number of a graph is the cardinality of a maximum critical independent set. This num-ber is a lower bound for the independence number and can be computed in polynomial-time. Any graph can be decomposed into two subgraphs where the independence number of one subgraph equals its critical independence num-ber, where the critical independence number of the other subgraph is zero, and where the sum of the independence numbers of the subgraphs is the inde-pendence number of the graph. A proof of a conjecture of Graffiti.pc yields a new characterization of König-Egervary graphs: these are exactly th...
