Hi John, 1. The decision variables are defined correctly. Alternatively, you can define them as below to remove the outer \(\texttt{for}\) loop. To represent the set \(T\) in the paper which is th...

Hi Sydney, Could you please help me to better understand your question? You mentioned that you would like to add a constraint such that at most one agent is assigned to an area. Your constraint be...

Hi Lukas, An easier approach might be to use the SolutionLimit parameter as a termination criterion. By setting the SolutionLimit parameter to 1, the optimization would terminate as soon as one fe...

Hi Grzegorz, Variable bounds are not a convenience feature for adding simple model constraints. Internally, Gurobi treats variable bounds differently than constraints. An optimization problem can h...

Hi Grzegorz, As you already know, we can think of dual variables as a vector of shadow prices for the righthandside vector of the primal problem. In your example, the \(i\)th constraint represen...

Hi Alexia, The parameters MIPGap and MIPGapAbs are indeed the performance metrics that can be used to quantify how good or bad a current solution is compared to the optimal solution. A MIPGap of 1...

Hi Murilo, When I say an unfeasible solution, I mean that the solution does not respect all restrictions. Sure, I get this. My point is MIPSOL callback is invoked only if a new incumbent solution...

Hi Elizabeth, We can think of improving the performance of Gurobi from two different aspects: modelling and parameter tuning. Modeling: Gurobi supports modelling simple general constraints such ...

Hi Murilo, My question is:Should I pass the value of all variables using setSolution()?or can i just pass the values of some variables? You have probably already checked the documentation of Mod...

Hi Yin, The error traces back to the part below in your snippet because you are multiplying the integer 1 by a GenExpr.  min_(gp.quicksum(y[t,0,k] for k in range(l_on1,L))  theta, d_on[t]) Tha...
