Detailed Description

template<class EOT>
class eoNormalVecMutation< 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>
eoNormalVecMutation< EOT >::eoNormalVecMutation ( 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 58 of file eoNormalMutation.h.

template<class EOT>
eoNormalVecMutation< EOT >::eoNormalVecMutation ( 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
for each component, the sigma is scaled to the range of the bound, if bounded
