Adding Quadratic constraint
回答済みHello, I am trying to add a Quadratic constraint to represent the ellipsoid in my model using Gurobipy. The constraint is of the type X.T * inv(covariance) * X at the moment, I use numpy multiplica...

MILP with quadratic constraints taking too long to solve
回答済みHello, I have a MILP model with one quadratic constraint in the form xT@A@x <= b. Without adding the quadratic constraint, model solves quickly. When I add the Qconstraint, model.optimize keeps run...
