FminCallbackInfo<T>.FCost Property

ILNumerics Ultimate VS Documentation

ILNumerics - Technical Application Development

The cost function value gives a measure of the penalty introduced by the constraints [readonly].

Namespace: ILNumerics.Toolboxes
Assembly: ILNumerics.Toolboxes.Optimization (in ILNumerics.Toolboxes.Optimization.dll) Version: 5.5.0.0 (5.5.7503.3146)

Syntax

Copy

public RetArray<T> FCost { get; }

Public ReadOnly Property FCost As RetArray(Of T)
	Get

Dim instance As FminCallbackInfo
Dim value As RetArray(Of T)

value = instance.FCost

Property Value

Type: RetArray<T>

Remarks

This property gives the value obtained by evaluating the cost function at XSub. Since fmin(Optimization.ObjectiveFunction<Double> , InArray<Double> , InArray<Double> , InArray<Double> , Optimization.ObjectiveFunction<Double> , Optimization.ObjectiveFunction<Double> , HessianUpdateMethod, Int32, Nullable<Double> , Nullable<Double> , OutArray<Double> , OutArray<Double> , Optimization.FminIterationCallback<Double> ) tries to minimize these violations decreasing values of FCost may indicate a progress towards an optimal solution. However, it is normal for an algorithm run to create non constantly decreasing values.
