GRBModel.addQConstr()

Add a quadratic constraint to a model. Multiple signatures are available.

Important note: Gurobi can handle both convex and non-convex quadratic constraints. The differences between them can be both important and subtle. Refer to this discussion for additional information.

GRBQConstr addQConstr ( GRBQuadExpr lhsExpr,
    char sense,
    GRBQuadExpr rhsExpr,
    String name )
    Add a quadratic constraint to a model.

    Arguments:

    lhsExpr: Left-hand side quadratic expression for new quadratic constraint.

    sense: Sense for new quadratic constraint (GRB.LESS_EQUAL or GRB.GREATER_EQUAL).

    rhsExpr: Right-hand side quadratic expression for new quadratic constraint.

    name: Name for new constraint.

    Return value:

    New quadratic constraint object.

GRBQConstr addQConstr ( GRBQuadExpr lhsExpr,
    char sense,
