Hi Jai, To illustrate how Mathematical Optimization (MO) can serve as an input to Machine Learning (ML), consider the following example: Example: Supply Chain Optimization Step 1: Mathematical Opti...

Hi Tao, The difference between using your custom Branch & Bound (B&B) algorithm and the Gurobi solver primarily lies in the optimization techniques and efficiency of the algorithms employed. Gurobi...

Hi, To determine if Intel or AMD CPUs support the use of the quad parameter in Gurobi, you should check if the processors support quadruple precision computations. According to the Gurobi reference...

Hi, The error you're encountering is due to how the generator expression is being handled within the m.addConstr method. Specifically, the generator expression inside m.addConstr needs to be correc...

Hi Param, To model a scenario where a variable can take only one value from a specified set at a particular time-step, and later use this variable for plotting or other purposes, you can utilize th...

Hi, When solving a multi-objective optimization problem in Gurobi, the results may not change between different priority settings for several reasons. Here are some potential explanations based on ...

Hi Zahra, To define your variable phi_0 such that it can never be zero but lies within the interval [−1,1], you can utilize auxiliary variables.  In your case, you want to enforce that phi_0 is eit...

Hi Wichitsawat, It looks like there might be a couple of issues in your P-median model implementation. 1. Model Optimization Call: You have correctly set up the model's objective and variables but ...

Hi Ariel, When you provide a starting solution to Gurobi—whether from a heuristic, a previous run, or any other source—Gurobi uses this solution in several ways that can impact the optimization ...

Hi Dejan, Solving a Lagrangian dual problem with Gurobi involves formulating the Lagrangian relaxation of your original problem and then using an iterative algorithm to solve it. This approach is p...
