Hi Sophie, You need to use the method Model.cbGetSolution(vars) to retrieve values from a new MIP solution. There is a clear example of how to do this at the bottom of the documentation page linke...

Hi Ilya, The parameters ImproveStartGap, ImproveStartNodes, and ImproveStartTime trigger solution improvement strategies where the Gurobi Optimizer only focuses on improving the incumbent to find ...

Hi Masoud, Thank you for your comments. The Gurobi MemLimit parameter is not just applicable to MIP problems. It is applicable to continuous problems too. For example, if the total amount of memo...

Hi Ahmad, After setting the parameter SolutionNumber to the \(i\)th best solution, the value of each variable can be accessed by querying the attribute Xn and not X (this attribute always reports...

Hi Elina, You can make your implementation cleaner and more compact like below: m.addConstrs((b * t[i] == l[i] for i in range(num_work)), name="fatigue")for i in range(num_work): m.addGenCons...

Hi Adrian, What are the coefficient values of variables \(x_i\) in your maximization model? Are they negative? The best way to figure out why your model is infeasible is to compute one of its IIS ...

Hi Masoud and Henrique, Gurobi versions >=9.5.0 supports a new parameter called MemLimit which allows the user to limit the total amount of memory available to Gurobi. If the Gurobi Optimizer need...

Hi Maryam, I am not sure that I fully understand the question. Could you please elaborate more on what the issue is? I would suggest posting a complete code snippet with all input such that we can...

Hi Laura, The added equality quadratic constraints makes the problem nonconvex and you need to explicitly set the parameter NonConvex=2 to tell Gurobi that it needs to solve a nonconvex problem. B...

Hi Xiaoyu, No, Gurobi does not directly support solving an optimization problem with an objective function in the form \(\frac{x^\prime Q x}{x^\prime P x}\). Please check the article on What types...
