Webm.setObjective(x*x + 2*y*y + 3*z*z) # A quadratic objective function m.addConstr(x + 2*y + 3*z >= 4) # Two linear constraints ... gurobipy 9.0 gives you tools to work more idiomatically with that data. • This is our first step towards making guropbipy matrix-friendly – let us know what you would ... WebNote that you will typically use overloaded operators to set the objective using matrix objects. The overloaded @ operator can be used to build a linear matrix expression or a quadratic matrix expression, which is then passed to setObjective. Arguments: Q: The quadratic objective matrix - a NumPy 2-D dense ndarray or a SciPy sparse matrix.
