Getting Binding Constraints

Answered

Hi, I want to get tight constraints at optimality for a linear model . It is possible to check equalities of constraints, but it would be better to have a simple Gurobi function to give binding constraints. Is there a function like this or is it possible to build?

Thank you

  After optimizing, you can check if each (linear) constraint's Slack attribute is sufficiently close to \(0\). For example, in Python:

  binding = [c for c in model.getConstrs() if abs(c.Slack) < 1e-6]
