[Lemon-user] number of STATE_TREE vars at end of network simplex (on connected graph)

[Matthew Galati]

Hi - I have a new example of where the number of STATE_TREE vars is not what
I had expected.

The number of nodes=1000, the number of basics = 987 at the end of
optimization. I checked and the graph is connected. Any ideas?

The data is here: http://coral.ie.lehigh.edu/~magh/tmp/net.dimacs2

Thanks,
Matt
