Description

This command sets the minimum temperature stopping criteria for a Simulated Annealing optimization.  This is equivalent to toggling the option in the dialog AND specifying the minimum temperature value.

Syntax

SetMzrAnnealStopBelowMinTemperature minTemp

Parameters

minTemp As Double

Minimum temperature value below which Simulated Annealing stops and final Simplex optimization proceeds.

Example

The following example sets the starting conditions for an optimization.  Note that in the example, SetMzrAnnealStopBelowMinTemperature is called after SetMzrAnnealStopAfterSteps.  This means that the stopping criteria is controlled by the min temperature setting.

Sub Main

    Dim multiStarts As Long

    Dim startTemp As Double

    Dim stopSteps As Long

    Dim stopMinTemp As Double

    Dim tempReduceFrac As Double

    multiStarts = 15

    startTemp = -1

    stopSteps = 50

    stopMinTemp = 0.001

    tempReduceFrac = 0.9

    SetMzrMultiStarts multiStarts

    SetMzrAnnealStartTemperature startTemp

    SetMzrAnnealStopAfterSteps stopSteps

    SetMzrAnnealStopBelowMinTemperature stopMinTemp

    SetMzrAnnealTemperatureReduceFraction tempReduceFrac

    Print "Multi Starts: " & Chr(9) & multiStarts

    Print "Start Temp: " & Chr(9) & startTemp

    Print "Stop Steps: " & Chr(9) & stopSteps

    Print "Stop Min Temp: " & Chr(9) & stopMinTemp

    Print "Temp Reduc. Frac: " & Chr(9) & tempReduceFrac

End Sub
