Hi,

I have an upper bound value for my problem and I'm going to solve the lower bound model. I need that the solving process of this lower bound will stop as soon as an integer solution is lower than the upper bound value.

I'm developing in C++.

Thanks in advance,

Domenico

I solved it.

Simply setting IloCplex::IntSolLim to 1 and introducing a constraint on my objective function:

objective <= UpperBoundValue

In this way, solving process stops and it gives me the feasible solution which I want.

Greetings,

Instead of adding a constraint on the objective you should set CPX_PARAM_CUTUP to your upper bound. This is simpler, numerically safer, and does not modify your model.
