public class JMetalAlgorithms
extends AlgorithmProvider

Algorithm provider for JMetal algorithms. Supports the following algorithms:

Name	Type	Properties
AbYSS	Real	populationSize, refSet1Size, refSet2Size, archiveSize, maxEvaluations, improvementRounds
CellDE	Real*	populationSize, archiveSize, maxEvaluations, feedBack, de.crossoverRate, de.stepSize
DENSEA	Any	populationSize, maxEvaluations
FastPGA	Any	maxPopSize, initialPopulationSize, maxEvaluations, a, b, c, d, termination
GDE3	Real*	populationSize, maxEvaluations, de.crossoverRate, de.stepSize
IBEA	Any	populationSize, archiveSize, maxEvaluations
MOCell	Any	populationSize, archiveSize, maxEvaluations, feedBack
MOCHC	Binary*	initialConvergenceCount, preservedPopulation, convergenceValue, populationSize, maxEvaluations, hux.rate, bf.rate
NSGAII	Any	populationSize, maxEvaluations
OMOPSO	Real*	populationSize, archiveSize, maxEvaluations, mutationProbability, perturbationIndex, epsilon
PAES	Any	archiveSize, bisections, maxEvaluations
PESA2	Any	populationSize, archiveSize, bisections, maxEvaluations
SMPSO	Real*	populationSize, archiveSize, maxEvaluations, pm.rate, pm.distributionIndex
SMSEMOA	Any	populationSize, maxEvaluations, offset
SPEA2	Any	populationSize, archiveSize, maxEvaluations

You may also append "-JMetal" to any algorithm name to use the JMetal implementation incase it is overridden by another implementation. For example, use "NSGAII-JMetal".

Unless the type is marked with *, the algorithm uses one of the types listed below. Note that only the types below are supported. Algorithms marked with * define operators specific to that algorithm. See the JMetal documentation for additional details.

Type	Operators	Parameters
Real	SBX, PM	sbx.rate, sbx.distributionIndex, pm.rate, pm.distributionIndex
Binary	Single-Point, Bit Flip	1x.rate, bf.rate
Permutation	PMX, Swap	pmx.rate, swap.rate

getAlgorithm

public Algorithm getAlgorithm(String name,
                              Properties properties,

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
