## 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 Definition at line 69 of file eoNormalMutation.h. References eoRealBaseVectorBounds::isBounded(), and eoRealBaseVectorBounds::range().
