Dysfunctional generate_random_graph

Reported by: irek.szczesniak@… Owned by: jewillco
Milestone: To Be Determined Component: graph
Version: Boost 1.44.0 Severity: Problem
Keywords: Cc: jewillco, david_abrahams

Description

The function generate_random_graph generates a graph with a different number of edges than I request. For instance, I request a network of 20 nodes and 20 non-parallel edges, but I get a network with 19 edges.

I'm attaching my test case.

Thanks,
Irek

Regretfully, I do not have time to fix this, or actually discuss whether this is bug, or what fix might be reasonable, so I'm unassigning this bug from myself.

I imagine this might have something to do with undirectness of the graph.
