Gurobi 12.0 onwardIn Gurobi 12.0, one can add a nonlinear constraint to set one variable equal to a nonlinear expression. This nonlinear expression can contain a variety of nonlinear operations, in...

Constraint Programming (CP) is a field of mathematical programming which focuses on finding feasible solutions subject to some given constraints. Theoretically, it is as hard as mixed integer progr...

It is possible to pointwise multiply an array and an MVar object:$$\begin{align} \begin{bmatrix} a_1 \\ a_2 \\ a_3 \end{bmatrix} \begin{bmatrix} x_1  \\ x_2  \\ x_3  \end{bmatrix}= \begin{bmatrix} ...

Currently, there is no direct way to set a lower bound for a minimization objective (or an upper bound in the case of maximization) in Gurobi.While providing an objective bound may seem like a good...

An indicator constraint \(y = f \rightarrow a^T x \leq b \), where \(x, y\) are variables, \(f\) is a given binary value, and \(a, b\) are constraint coefficients, states that if the binary indicat...
