Remarks
A LinearConstraint object represents a linear constraint in a OptimizationModel. LinearConstraint objects are created using the [o:OptimizationModel.AddLinearConstraint] method of the OptimizationModel class.
Each constraint has a Name, which may be generated automatically. The LowerBound and UpperBound properties specify the left and right hand sides of the constraint.
Properties
| Constraint |
Gets the type of row.
(Inherited from Constraint) |
| Gradient |
Gets the current value of the constraint gradient.
(Inherited from Constraint) |
| IsLinear |
Gets whether the constraint is linear.
(Overrides Constraint.IsLinear) |
| Lower |
Gets or sets the lower bound of the variable.
(Inherited from OptimizationModelEntity) |
| Name |
Gets the name of the variable.
(Inherited from OptimizationModelEntity) |
| Position |
Gets the position of the current instance in the collection.
(Inherited from OptimizationModelEntity) |
| Upper |
Gets or sets the upper bound of the variable.
(Inherited from OptimizationModelEntity) |
| Value |
Gets the current value of the constraint.

Methods
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) |
| Evaluate |
Evaluates the constraint at the specified point.
(Overrides Constraint.Evaluate(Vector<Double>)) |
| Evaluate |
Evaluates both the constrain value and its gradient in one operation.
(Overrides Constraint.EvaluateConstraintAndGradient(Vector<Double>)) |
| Evaluate |
Evaluates the gradient of the constraint at the specified point.
(Overrides Constraint.EvaluateGradient(Vector<Double>)) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object) |
| Get | Serves as the default hash function. (Inherited from Object) |
| Get | Gets the Type of the current instance. (Inherited from Object) |
| Memberwise | Creates a shallow copy of the current Object. (Inherited from Object) |
| ToString | Returns a string that represents the current object. (Inherited from Object) |
