[Lemon-user] NegMap problem

[Attila Bernáth]

Dear Developers,

I am having a strange phenomenon. I read a graph in which a spanning
tree is specified (with a bool edgemap). Then I pass this info to a
class (CutLp). I want to work with both the tree and the rest as
subgraphs, so I use FilterEdges and NegMap (for this second), but it
seems that the negation does not occur for me. Can you help me to sort this
out?

I attach the example.

Thank you very much!

Attila
