Hi, consider the product of a binary variable x, with an integer variable y. How to efficiently linearize this term? Also is it is better to linearize this term, or  gurobi solver can handle it? Th...

I have a mixed integer linear program. My objective function involves the sumation of binary variables and quadratic terms of continuous variables. When i execute the model optimize function i get ...

Could i define 3-index variable using addVars where for the first index when it's value is less than 2 it will be a binary variable, otherwise it will be a continuous varible.

In case of an integer programming problem, i would like to add in the objective function an integer division of a decision variable with a constant number. Is there any efficient way to implent thi...

Consider a binary variable \(x_s(t)\), and a continuous variable \(z_s(t) = t - t_s\), where \(t_s\) is a known constant. We define a conditional variable \(sr_s(t) = x_s(t)\) if \(0 \leq z_s(t) < ...
