OptimizationFminIterationCallbackT Delegate

public delegate void FminIterationCallback<T>(
	FminCallbackInfo<T> info
)

Public Delegate Sub FminIterationCallback(Of T) ( 
	info As FminCallbackInfo(Of T)
)

Dim instance As New FminIterationCallback(Of T)(AddressOf HandlerMethod)

Parameters

info

Type: ILNumerics.ToolboxesFminCallbackInfoT
Instance of the FminCallbackInfoT class.

Type Parameters

T

element type, currently always: System.double

If user provides a function as the callback parameter of fmin(OptimizationObjectiveFunctionDouble, InArrayDouble, InArrayDouble, InArrayDouble, OptimizationObjectiveFunctionDouble, OptimizationObjectiveFunctionDouble, HessianUpdateMethod, Int32, NullableDouble, NullableDouble, OutArrayDouble, OutArrayDouble, OptimizationFminIterationCallbackDouble), the function gets called at each major iteration. The info parameter provides extensive information about the state of the optimization process, including details of the subproblem solved in that iteration.

Callback is a user defined function which gets called by fmin(OptimizationObjectiveFunctionDouble, InArrayDouble, InArrayDouble, InArrayDouble, OptimizationObjectiveFunctionDouble, OptimizationObjectiveFunctionDouble, HessianUpdateMethod, Int32, NullableDouble, NullableDouble, OutArrayDouble, OutArrayDouble, OptimizationFminIterationCallbackDouble) and allows access to the information by means of properties of info.
