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!!!

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
