Title:  Clique coverings of the edges of a random graph. (In English)
Source:  Combinatorica 13, No.1, 1-5 (1993).
Review:  Bounds on the clique number of the random graph (with the edge probability of ½) are derived. It is proved that almost every graph with n vertices has a collection of O(n2 ln\ln n/(ln n)2) cliques that cover all its edges. It is also proved that for almost every graph with n vertices, in order to cover all its edges it is necessary to use at least (1-\epsilon)n2/(2 ln n)2 cliques.
