Hi Oscar, You are basically right, if the gap is below the value set by the MIPGap parameter and the desired number of different solutions is found (PoolSolutions), then the solver should terminate...

Hi Ruben, Just to be sure, your model is a pure LP without integer variables? As I mentioned before, the barrier termination criteria are quite complex and do not only consider the BarConvTol param...

Hi Ruben, The parameter BarConvTol is related to the complementarity (second last column in the barrier output). The computation of this complementarity measure is quite elaborate and cannot be eas...

Hi Sony, We did not try so far, but there is an ARM64 build of the solver that could help here. Best regards,Mario

Hi, It seems your status variable is a given list of constants, not a Gurobi variable, right?What exactly are model variables and what is given input data?It seems for example that diffCharge are m...

Hi Ye, Sorry, I am not too much into the theory of normal distributions. Regarding modeling divisions: Sometimes, the divisions can be reformulated such that they can be handled in Gurobi. For exam...

Hi Ye, Gurobi variables cannot be directly used in arbitrary math functions, you have to use general constraints to deal with non-linear/non-quadratic terms. You might need to re-formulate your fun...

Please take a closer look at the paper I mentioned before. The flow conservation constraints (6) are defined per customer and sum up all incoming flow minus all outgoing flow. The same thing applie...

First of all, you can safely remove the k index, since you visit each customer exactly once. You just limit the number of arcs going out of the depot by m. The capacity constraints 5.72 can be repl...

Hi, Ok, I understand now. You might be able to handle your product also for $n>2$ by introducing additional variables in the following way: x_1 * x_2 = y_2y_2 * x_3 = y_3...y_{n-1} * x_n = c Best r...
