I have an optimization problem that involves two possible objective functions. One variation of the problem involves me maximizing one of the objective functions such that the second objective func...

Hello, I am calling Gurobi using the Python API from R using the reticulate package. In R, I have wrapped my Python call in outer functions as I perform a series of computations. However, I want to...

Hello, There is a parameter I know makes my model solve orders of magnitude faster (PreQLinearization = 0). With it, the model takes less than 0.1 seconds to solve, without it, it won't solve in th...

I am currently working a project in which I use Gurobi many times (as the inner most loop of a few nested loops). Each time, I construct a model in which I determine if an individual will participa...

I wanted to know if it was possible to use Gurobi to test if a feasible solution is the optimal solution to a nonlinear binary programming problem. Is it possible to have Gurobi use the solution I ...

I am working on a problem that is a modified version of a two-knapsack knapsack problem. I am able to find the optimal choices by using Gurobi. However, I would like to estimate a coefficient that ...

Hello, I am attempting to solve this problem where all variables, besides the Xi and Yi choice variables, are fixed/observed in data. Note than equation (43) and (44) are the same, simply reformula...
