Detailed Description

DoubleGenotype class.

Description

A gene is a double value within the range specificed by minValue and maxValue methods.
This is an abstract class defining the common interface among different encoding of double numbers inside a gene.

Constructor & Destructor Documentation

DoubleGenotype	(	unsigned int	numGenes,
		double	min,
		double	max,
		unsigned int	bitPrec
	)

Construct a un-initialized DoubleGenotype

Parameters:

numGenes	is the number of double values contained by this DoubleGenotype
max	is the maximum absolute value represented
min	is the minimum absolute value represented
bitPrec	is the bit precision used for encode a double value

Warning:

you must explicity call randomize() to get a randomized Genotype

Note:

the Genotype::size() return the number of bits of underlying data, while numGenes is the actual numbers of genes of this DoubleGenotype. They are related by the multiplication:
