orbital.algorithm.evolutionary
Class Gene.Fixed

java.lang.Object
  orbital.algorithm.evolutionary.Gene.BitSet
      orbital.algorithm.evolutionary.Gene.Fixed

All Implemented Interfaces:

java.io.Serializable, Gene

Enclosing interface:

Gene

public static class Gene.Fixed
extends Gene.BitSet

Fixed point gene data.

This implementation uses a Gene.BitSet encoded fixed-point numbers as gene data.

Note that default uniform mutations and recombinations have a dramatic effect on bit string encoded values.

Constructor Detail

Gene.Fixed

public Gene.Fixed(int integerGranularity,
                  int fractionalGranularity)

Method Detail

get

public java.lang.Object get()

Description copied from interface: Gene

Get the gene interpretation value.

Useful for interpreting a gene for fitness evaluation and interpretation of solutions.

Specified by:

get in interface Gene

Overrides:

get in class Gene.BitSet

Returns:

the Object represented by this gene. Interprets gene by decoding its data.

set

public void set(java.lang.Object n)

Description copied from interface: Gene

Set the gene value.

Consider setting fitness to Double.NaN due to the change to remind evaluator.

Specified by:

set in interface Gene

Overrides:

set in class Gene.BitSet

Parameters:

n - the Object this gene should represent. Encodes the value such that this gene represents the given object.

getIntegerGranularity

protected int getIntegerGranularity()

Get the number of bits for the integer part.

getFractionalGranularity

protected int getFractionalGranularity()

Get the number of bits for the fractional part.

getSignGranularity

protected int getSignGranularity()

Get the number of bits for the sign part.
