How do I access constraints and variables efficiently with Compute Server or Instant Cloud?
When using Gurobi Remote Services, it is important to take communication overhead into consideration, especially if the Compute Server is not on your local network. There are a couple of mechanism...

Resolved in Gurobi v9.1.0: Feasibility relaxations of multi-objective models
Affected versions: Gurobi v9.0.0, v9.0.1, v9.0.2, v9.0.3 Resolved in version: Gurobi v9.1.0 Issue When a model is infeasible, you can use Model.feasRelax() or Model.feasRelaxS() to create a feasibi...

How do I model a piecewise-linear function of more than one variable?
Although Gurobi's support for piecewise-linear functions is limited to univariate functions, it can still be useful for approximating multivariate functions. Consider the following multivariate fun...

How do I determine why my model is infeasible?
When solving optimization models, certain scenarios may arise where the defined constraints cannot be fulfilled, leading to what is known as an infeasible model. Such situations can occur either du...

How do I inject a solution calculated in a separate process?
In some cases, you may be interested in running a heuristic in parallel to the Gurobi optimization and inject a found heuristic solution into Gurobi's solve process. To do so, you need to establish...

Why is there an output lag in the log in my Jupyter notebook?
When solving a model in a Jupyter notebook, the log output in the Jupyter notebook may lag one entry behind the log file. For example, the file may contain: Root simplex log...Iteration Objectiv...
