simple undirected weighted graphs

This dataset contains over than 60 flow matrices of simple undirected weighted graphs. These graphs have the following characteristics :

|V| \in {20, 50, 100, 300, 500, 700, 800, 900, 1000,  2000, 3000}

For every graph's order, 10 instances are generated each of them corresponds to one of the following densities :

Densities \in {0.05, 0.1, 0.25, 0.5, 0.75, 0.9, 1.0}

The nodes are grouped in clusters with a very strong edges and the rest of edges have all the same weight equal to 1. The clusters size corresponding to each of the above graphs orders.

clusters \in {5, 5, 10, 30, 50, 70, 80, 90, 100, 400, 500 };
