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 ( GRBQuadExpr lhsExpr,
    char sense,
    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: Name for new constraint.

Return value:

New quadratic constraint object.

GRBQConstr AddQConstr ( GRBTempConstr tempConstr,
    string name )

Add a quadratic constraint to a model.

Arguments:

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

name: Name for new constraint.

Return value:

New quadratic constraint object.
