[Lemon-user] Capacity on the nodes

[mariam dervish]

Hello all,I am very new here and trying to build a directed graph for a multi commodity minimum cost network. I need help on how to add capacity to the transshipment nodes. I know how to add capacity to the arcs, but in my case, the sum of what enters and exits all nodes with supply =0, needs to be restricted. Thanks,Mary
