[Lemon-user] Running Network Simplex in modified versions of the network

[RODRIGO MESA ARANGO]

Dear Lemon Users,

I'm learning Lemon to develop an algorithm. I'm planning to:
1. Set original network
2. Run min-cost flow algorithm (currently network simplex)
3. Modify network based on results (add/remove arcs, modify capacities and
costs)
4. Repeat 2 over modified network up to a stopping criterion

I used a SmartDigraph and could run network simplex but cannot modify the
network (add/remove/modify arcs) iteratively.

Q1. Can you please suggest me how to modify the network?
Q2. What digraph structures are better for network simplex (or min-cost
flow algorithms in general) and how to use them?

Thank you. Have a nice day!
