Hi Ebru, Have you tried using the GRBModel.addGenConstrPow() method? To model \( z^{1.5} \leq v\), you can have: z = model.addVar(name="z")y = model.addVar(name="y") v = model.addVar(name="v")mo...

Hi Anastasios, Are you using a Linux machine? Have you checked our How do I use Gurobi with PyCharm (Section: Note for Linux users) article or the Software Installation Guide (for Linux)? You like...

Hi Aldo, You see this error because you are trying to sum over Gurobi general expressions (GenExpr). The error traces back to the part below: sum(max_((beta - (stocks @ ret[i])), 0) for i in ra...

Hi Tobias, Simplex algorithms are sequential methods and are not amenable to parallelization. Therefore, increasing the number of cores does not have any impact. Since the barrier algorithm outpe...
-
Hi Tobias, One point before getting into your question: It seems that you are using Gurobi 9.1.1, we always recommend using the latest version of Gurobi which is 9.1.2 right now. The log file sh...

Hi Veronika, Some of the presolve procedures such as dual presolve/presolving reductions rely on knowing the feasible region in its entirety. Since it is not possible to know the whole feasible re...

Hi Tobias, Have you checkout the article on "Does using more threads make Gurobi faster?"? Increasing the number of threads does not necessarily speed up the optimization algorithm. How many ...

Hi Maik, You can define the decision variables as binary variables \(x_{ij} \) being equal to 1 if order \(i\) is delivered by product \(j\) and to 0 otherwise. Let us further define \(r_i\) to re...
-
Hi Andres, The Gurobi academic license does not have any restriction. It is the same full-featured version offered to commercial users. The amount of memory that you can access depends on the hard...

Hi Bahareh, Do you have the following case where \(u \in [13, 17] \cup \{0\}\)? \[y = \begin{cases} 89 + 8.9 u - 5.95(u-15) & 15 \leq u \leq 17, \\ 89 + 8.9 u & 13 \leq u < 15, \\ 0 & u = 0. \en...
