GRBModel::addQConstr()


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 ( const GRBQuadExpr& lhsExpr,
    char sense,
    const GRBQuadExpr& rhsExpr,
    string name="" )

Add a quadratic constraint to a model.

Arguments:

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

sense: Sense for new quadratic constraint (GRB_LESS_EQUAL, GRB_EQUAL, or GRB_GREATER_EQUAL).

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

name (optional): Name for new constraint.

Return value:

New quadratic constraint object.

GRBQConstr addQConstr ( const GRBQuadExpr& lhsExpr,
    char sense,
    GRBVar rhsVar,
    string name="" )

Add a quadratic constraint to a model.

Arguments:

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

sense: Sense for new quadratic constraint (GRB_LESS_EQUAL, GRB_EQUAL, or GRB_GREATER_EQUAL).

rhsVar: Right-hand side variable for new quadratic constraint.

name (optional): Name for new constraint.

Return value:

New quadratic constraint object.

GRBQConstr addQConstr ( GRBTempConstr& tc,
    string name="" )

Add a quadratic constraint to a model.

Arguments:

tc: Temporary constraint object, created using an overloaded comparison operator. See GRBTempConstr for more information.

name (optional): Name for new constraint.

Return value:

New quadratic constraint object.
