DecisionVariable Class

Represents a variable in a OptimizationModel.

Definition

Namespace: Numerics.NET.Optimization
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 9.0.4
C#
public class DecisionVariable : OptimizationModelEntity

Remarks

The DecisionVariable class represents a variable in a OptimizationModel. DecisionVariable objects are created using the linear program's AddVariable(String, Double, Double) method of the OptimizationModel class. They may also be created when a constraint is added using the [o:OptimizationModel.AddLinearConstraint] method.

Each variable has a Name, which may be generated automatically. The LowerBound and UpperBound properties specify the lower and upper bounds. After the solution of the model has been computed, the Value property returns the value of the variable in the optimal solution.

Properties

IsInteger Gets or sets whether the variable is restricted to integer values.
LowerBound 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)
UpperBound Gets or sets the upper bound of the variable.
(Inherited from OptimizationModelEntity)
Value Gets the value of the variable after the optimal solution has been found.

Methods

EqualsDetermines whether the specified object is equal to the current object.
(Inherited from Object)
FinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object)
GetHashCodeServes as the default hash function.
(Inherited from Object)
GetTypeGets the Type of the current instance.
(Inherited from Object)
MemberwiseCloneCreates a shallow copy of the current Object.
(Inherited from Object)
ToStringReturns a string that represents the current object.
(Inherited from Object)

Operators

Implicit(DecisionVariable to Double) Implicitly converts a decision variable to a double-precision floating-point number.
