Hello Everyone,I'm working on a python code to input matrices into CPLEX solver. I have most of my code running fine but as of now, I don't know how to express this constraint. My objective is to minimize the number of nodes. I have got one of the weirdest looking constraints which I don't know how to express in Python because python basically takes matrices and inputs them into cplex. My constraint is as below. This was what I wrote in AMPL minimize phy_nodes: sum {w in PHY_NODES} x_ns[w] ; s.t. Phy_nodes_Eq{w in PHY_NODES, dns in DEMAND}: x_ns[w] = 1 ==> x_SGW[dns, w] + x_PGW[dns, w] + x_MME[dns, w] + x_IMS[dns, w] + x_PoP[dns, w] >= 1 else x_SGW[dns, w] + x_PGW[dns, w] + x_MME[dns, w] + x_IMS[dns, w] + x_PoP[dns, w] = 0; Could you help me fix this problem? Thank You
This is more a CPLEX question than a Python question. (Or rather a question about some Python/Cplex interface.) Do you have access to any kind of a CPLEX forum or a Cplex-via-Python forum? I think that's much more likely to get you an answer.
