All Implemented Interfaces:

GeneticOperator, java.io.Serializable

public class Stretcher

extends java.lang.Object

implements GeneticOperator

Strecher is a Genetic Operator that will add length to a genotype.

The amount it is streched by is configurable and even randomized between limits.

What data is placed in the new section is also configurable.

The position where this new data will be inserted/appended is also configurable.

NOTE: ONLY (FIXED) LENGTH OF NEW SECTION & POS OF SOURCE OF DATA TO COPY CONFIGURABLE

Constructor Detail

Stretcher

public Stretcher()

Creates new Stretcher. Default values are used for stretchAmount = 1 and for copyFrom = -1 (this means no data is copied, all zeros are added).

Stretcher

public Stretcher(int stretchAmountP,
                 int copyFromP)

Creates new Stretcher.

Parameters:

stretchAmountP - Fixed amount to add at end of genotype.

copyFromP - Where to get data from to fill in new section.

Method Detail

operate

method that adds genotypes to the new population by extracting some from the old one and manipulating them in some way.

Specified by:

operate in interface GeneticOperator

Parameters:
