I need to find all feasible solutions of my milp model no matter if they are optimal or not. I have used the poolsolutions for this with the parameter "PoolSolutions = 2000000000" (max possible value). However, when I try this model with PoolSearchMode=2, I get different number of solutions in comparison with optimizing the same model with PoolSearchMode=1.
I suppose that solving a model with PoolSearchMode=2 should return the same number of solutions as solving the model with PoolSearchMode=1, as far as PoolGap equals infinity (its default value as in my case). Am I correct? If yes, what is the reason of the above observation?
I do appreciate any guidance in advance!
