Good morning,
I would like to ask you for help in understanding how to stop the optimization that I do via intlinprog (R2014b) when it is very close to the optimal. I have set various parameters but if it was not for the limit that I give it for the nodes (1500000) it would not stop. I attach an example in which LP calculates an optimal equal to -2885,... Branch and Bound starts the calculation and already in the first steps it gets very close and stops for many nodes on -2882 which could already be an optimal value at which to stop without making it wait any longer. How do I set the options so that this gap is sufficient to stop the calculation? I attach an image of a calculation and the parameters used.
