Very helpful! Thanks a lot! My graph is directed and I was looking for something like this as you gave above map<edge, GRBVar> *x = new map<edge, GRBVar>[num_vertices]; for (int i = 0; i < num_vert...

Hi, In case you use Gurobi with c++, you can use the following  // Env and model GRBEnv env = GRBEnv(); GRBModel model = GRBModel(env); //Avoid printing the LP solution in consolemodel.set(GRB_IntP...

Thanks Eli. I could use it but in a different way. I needed to define a map assigning a distinct integer number to each edge as I need to access the source and target of each edge through my constr...

Thanks Eli for your reply! As most of the graphs I'm using are sparse, I would like to define a two dimensional array in which the first dimension represents the vertices and the second dimension r...

Hi Eli, I want to define a two dimensional array in which the first dimension representing the vertices in a graph and the second dimension representing the edges in the graph. This means that the ...
