Detailed Description

template<class EOT>
class eoOneToOneBreeder< EOT >

eoOneToOneBreeder: transforms a population using

• an operator that MODIFIES only one parent from the populator (though it can use any number aside) and thus generates ONE offspring)
• a local replacement between the parent and its offspring

Typically, Differential Evolution (Storn and Price 94) and Deb et al's G3 can be built on this

Parameters:

_op	a general operator (must MODIFY only ONE parent)

Member Function Documentation

template<class EOT >

void eoOneToOneBreeder< EOT >::operator()	(	const eoPop< EOT > &	_parents,
		eoPop< EOT > &	_offspring
	)		[inline, virtual]

The breeder: iteratively calls the genOp ONCE on a selective populator after having recorded the parent Then does the replacement.

Parameters:

_parents	the initial population
_offspring	the resulting population (content -if any- is lost)

Implements eoBF< const eoPop< EOT > &, eoPop< EOT > &, void >.
