IntegralityFocus affects solution of non-convex, continuous models
回答済みHi, when solving a continuous, non-convex model with Gurobi, I noticed that setting the IntegralityFocus parameter to 1 affects the returned solution (the parameter was set due to the calling conte...

MIP bound is greater than reported incumbent solution and reported solution is suboptimal
回答済みHi, when solving a MIP using ConcurrentMIP (as well as some other non-default parameter settings, see linked log-file), Gurobi reports multiple weird things: The reported bound is greater than the...
