public abstract class Constraint : OptimizationModelEntity- Inheritance
- Object → OptimizationModelEntity → Constraint
- Derived
Remarks
A Constraint object represents a constraint in a OptimizationModel. Constraint objects are created using the AddLinearConstraint(String, ConstraintType, Double) 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. |
| Gradient | Gets the current value of the constraint gradient. |
| IsLinear | Gets whether the constraint is linear. |
| 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. |
| Evaluate | Evaluates both the constrain value and its gradient in one operation. |
| Evaluate | Evaluates the gradient of the constraint at the specified point. |
| 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) |
