Dear Hamza, I see that you're using Gurobi Optimizer v9.0.3, but the current version is v9.1.1.Could you please try to solve your model instance with the latter? We constantly strive to fix known b...

As long as  you model doesn't have numerical issues, you can definitely trust the optimal solution reported by our Solver

As explained in the section MIP Logging of our reference manual, The sub-section Current Node of the Branch-and-Cut (B&C) Tree Search provides information on the specific node that was explored at ...

Our solver does not rely on enumeration to see whether a point is feasible or not. In fact, this approach does not work on real-world problems, as they typically have an astronomical number of feas...

To get non-overlapping rectangles of the same area, you can solve the following feasibility model (implemented in Python): import gurobipy as gpfrom gurobipy import GRBTOTAL_HEIGHT = 5TOTAL_WIDTH =...

You can specify this behavior by setting the parameter MIPGap.

Dear Álvaro, Recall that PCA is not scale invariant. It's very important to check whether a specific implementation centers and/or scales the data matrix before finding the principal components. As...

Dear Parijat, That's indeed possible. Please find below an assignment problem I implemented with the Gurobi-Python interface: import gurobipy as gpfrom gurobipy import GRBresources = ["r1", "r2", "...

Dear Daniel, Let flag be a binary variable that takes on the value of one if and only if the general integer variable storage is strictly greater than zero (i.e. flag=0 when storage=0). Also, let B...

Dear Ray, I'd use two types of general constraints, namely model.addGenConstrAbs() and model.addGenConstrIndicator(), along with a few auxiliary variables. In Python, this would look as follows:   ...
