Detailed Description

A genome which uses bits to store values.

Public Member Functions
	BitGenome (Ishtar::InputStream *stream)
	Constructor, deserialize from stream.
	BitGenome (size_t size)
	Constructor, size bits.
bool	getBit (size_t pos)
	Returns bit at pos.
bool	operator[] (size_t pos)
	[] operator to get bit at pos, convenient
void	setBit (size_t pos, bool bit)
	Set bit at pos.
void	seek (size_t pos)
	Seel to pos.
size_t	getLength ()
	Returns the length in bits.
size_t	getWordCount ()
	Returns the number of unsigned in the bits storage. Usefull for specific implementations.
void	setWord (size_t pos, unsigned val)
	Directly set an unsigned in the bits storage. Usefull for specific implementations.
unsigned	getWord (size_t pos)
	Directly get an unsigned in the bits storage. Usefull for specific implementations.
unsigned	getUnsignedIntRaw (unsigned precision)
	Get a value of type unsigned int on range [0..2^precision-1] by directly reading bit per bit, increment reading position.
template<typename T>
T	getValue (unsigned bitCount)
	Get a value of type T on range [0..1] using bitCount bits, increment reading position.
template<typename T>
T	getValueRange (unsigned bitCount, T min, T max)
	Get a value of type T on range [min..max] using bitCount bits, increment reading position.
virtual double	getDouble (double min, double max)
	Get a value of type double on range [min..max] using defaultPrecision bits, increment reading position.
virtual float	getFloat (float min, float max)
	Get a value of type float on range [min..max] using defaultPrecision bits, increment reading position.
virtual int	getSignedInt (unsigned precision, int min, int max)
	Get a value of type signed int on range [min..max] using precision bits, increment reading position.
virtual unsigned	getUnsignedInt (unsigned precision, unsigned min, unsigned max)
	Get a value of type unsigned int on range [min..max] using precision bits, increment reading position.
virtual void	resetReading (void)
	Set reading position to 0.
void	setDefaultPrecision (unsigned p)
	Number of bits used for floats and doubles.
virtual void	randomize (void)
	Randomize genome content.
virtual void	mutate (void)
	Mutate genome content.
virtual void	cross (const Genome *other)
	Cross genome content over other.
virtual Genome *	clone (void)
	Clone this genome, returns the new genome.
virtual void	save (Ishtar::OutputStream *stream)
	Save the genome to a stream.
Protected Member Functions
bool	checkBoundWord (size_t pos)
	return true if word pos is within bound, returns false or assert otherwise depending on Genome::disableAssertion
Protected Attributes
std::valarray< unsigned >	bits
	real datas of the genome
size_t	length
	length in bits of the genome
Ishtar::Variable< double >	mutationProbability
	cached ishtar parameters
Ishtar::Variable< unsigned >	defaultPrecision
	cached ishtar parameters
size_t	readPos
	positiong for reading, internal machinery
