Detailed Description

template<typename GeneType>
class galib::ArithmeticCrossover< GeneType >

Performs arithmetic (convex) crossover.

Children are produced as a linear combination of parent genes: Child1 = alpha * Parent1 + (1 - alpha) * Parent2 Child2 = alpha * Parent2 + (1 - alpha) * Parent1 where alpha is a random value in [0, 1] chosen once per crossover event.

Template Parameters

GeneType

The numeric type of the genes.

std::pair< Individual< GeneType >, Individual< GeneType > > galib::ArithmeticCrossover< GeneType >::crossover ( const Individual< GeneType > &  parent1, const Individual< GeneType > &  parent2  )

inlineoverridevirtual

Produces children via linear interpolation of parent genes.

Parameters

parent1	First parent.
parent2	Second parent.

Returns

Pair of children.

Exceptions
