public class StandardAlgorithms
extends AlgorithmProvider

A provider of standard algorithms. The following table contains all available algorithms and the customizable properties. These properties are tailored for real-valued operators. If using a different representation, see OperatorFactory for the appropriate parameters. See the user manual for a more detailed description of the algorithms and parameters.

Description copied from class: AlgorithmProvider

Returns the algorithm with the specified name, or null if this provider does not support the algorithm. An optional set of properties may be provided to further define the algorithm; however, the provider is expected to supply default properties if none are provided.

Specified by:

getAlgorithm in class AlgorithmProvider

Parameters:

name - the algorithm name

properties - optional properties for the algorithm

problem - the problem

Returns:

the algorithm with the specified name, or null if this provider does not support the algorithm
