)

abstract StopAtIntermediateIteration : 
        iteration : int * 
        levels : LinkedList<float> * 
        parameters : LinkedList<DoubleMatrix> -> bool 
override StopAtIntermediateIteration :

        levels : LinkedList<float> * 
        parameters : LinkedList<DoubleMatrix> -> bool 

Parameters

iteration

Type: SystemInt32
The current iteration identifier.

levels

Type: System.Collections.GenericLinkedListDouble
The performance levels achieved in previous iterations by a SystemPerformanceOptimizer executing in this context.

parameters

Type: System.Collections.GenericLinkedListDoubleMatrix
The sampling parameters applied in previous iterations by a SystemPerformanceOptimizer executing in this context.

Return Value

An iteration is defined as intermediate for a SystemPerformanceOptimizationContext if it is greater than MinimumNumberOfIterations, and less than MaximumNumberOfIterations.

For intermediate iterations, method StopAtIntermediateIteration(Int32, LinkedListDouble, LinkedListDoubleMatrix) is called to check if a Cross-Entropy program executing in this context should stop or not.

By default, the method controls if, in the last MinimumNumberOfIterations iterations, the levels achieved by the program remain constant, and, if so, return true; otherwise returns false.
