Xpress range constraint
Using the latest Xpress interface I can add a constraint x_i + y_i <= UB_i for all i like this: xprsProb.addConstraints(nrNodes, i -> sum(x+y).leq(UB)); How can I add a range constraint like: LB_i...
Hi Joris,
I think the method you are looking for is "in":
xprsProb.addConstraints(nrNodes, i -> sum(x+y).in(UB, LB));
