[Lemon-user] switching arcs on and off

[Michal Kaut]

Hello,

I have just found Lemon and it looks very promising, so I would like to
give a try. There is, however, one particular thing I need and that I
did not see in the documentation: I am solving shortest-path problem on
many different sub-sets of one given set. Currently, I am using Coin's
Cgc classes, which have the possibility to activate and deactivate arcs,
so one does not need to rebuild the network all the time.

Does Lemon have such a possibility?
And if not, any idea how difficult it could be to implement it? (I
definitely do not want to build a new network for each case.)


Thanks a lot in advance.

Regards,
Michal Kaut
