Detailed Description

template<class EOT>
class eoEsChromInit< EOT >

Random Es-chromosome initializer (therefore derived from eoInit)

This class can initialize four types of real-valued genotypes thanks to tempate specialization of private method create:

• eoReal just an eoVector<double>
• eoEsSimple + one self-adapting single sigma for all variables
• eoEsStdev a whole std::vector of self-adapting sigmas
• eoEsFull a full self-adapting correlation matrix

Constructor & Destructor Documentation

template<class EOT>

eoEsChromInit< EOT >::eoEsChromInit	(	eoRealVectorBounds &	_bounds,
		double	_sigma = 0.3,
		bool	_to_scale = false
	)		[inline]

Constructor.

Parameters:

_bounds	bounds for uniform initialization
_sigma	initial value for the stddev
_to_scale	wether sigma should be multiplied by the range of each variable added December 2004 - MS (together with the whole comment :-)

Definition at line 74 of file eoEsChromInit.h.

template<class EOT>

eoEsChromInit< EOT >::eoEsChromInit	(	eoRealVectorBounds &	_bounds,
		const std::vector< double > &	_vecSigma
	)		[inline]

Constructor.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Specify individual initial sigmas for each variable.

Parameters:

_bounds	bounds for uniform initialization
_vecSigma	initial value for the stddev

[inline, private]

Create intializer.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Adaptive mutation through a std::vector of sigmas

Todo:

Should we scale sigmas to the corresponding object variable range?
