There are four classes of problems, each generated from different parameterizations of popular complex network topologies. Parameterization is discussed in the aforementioned paper. The file format is as follows: line 1 contains the number of vertices. The remaining lines contain the vertex number, followed by a colon, and a list of connected vertices. That is, this representation is an adjacency list of the undirected graph. Download all graphs here
