Determining the Stability Number of a Graph.
Abstract
Certain rules for deriving upper bounds on the stability number of a graph are formalized. The resulting system is powerful enough to (1) encompass the algorithms of Tarjan's type and (2) provide very short proofs on graphs for which the stability number equals the clique-covering number. However, the main result shows that for almost all graphs with a (sufficiently large) linear number of edges, proofs within the system must have at least exponential length.
