Detailed Description

template<class EOT>
class eoNormalMutation< EOT >

Simple normal mutation of a std::vector of real values.

The stDev is fixed - but it is passed ans stored as a reference, to enable dynamic mutations (see eoOenFithMutation below).

As for the bounds, the values are here folded back into the bounds. The other possiblity would be to iterate until we fall inside the bounds - but this sometimes takes a long time!!!

Constructor & Destructor Documentation

template<class EOT>

eoNormalMutation< EOT >::eoNormalMutation	(	double &	_sigma,
		const double &	_p_change = 1.0
	)		[inline]

(Default) Constructor.

The bounds are initialized with the global object that says: no bounds.

Parameters:

_sigma	the range for uniform nutation
_p_change	the probability to change a given coordinate

Definition at line 131 of file eoNormalMutation.h.

template<class EOT>

eoNormalMutation< EOT >::eoNormalMutation	(	eoRealVectorBounds &	_bounds,
		double	_sigma,
		const double &	_p_change = 1.0
	)		[inline]

Constructor with bounds.

Parameters:

_bounds	an eoRealVectorBounds that contains the bounds
_sigma	the range for uniform nutation
_p_change	the probability to change a given coordinate
