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> GradL { get; }

Public ReadOnly Property GradL As RetArray(Of T)
	Get

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

value = instance.GradL

Property Value

Type: RetArrayT

Remarks

Each major iteration in a constrained optimization problem involves the minimization of an unconstrained subproblem (Lagrangian). The minimum of that subproblem is expected to have a gradient of 0. The actual value returned in GradL serves as a hint for the quality of the solution of the current subproblem.
