Constructor Detail

DefaultCrossoverRateCalculator

public DefaultCrossoverRateCalculator()

Method Detail

calculateCurrentRate

public int calculateCurrentRate()

Calculates the dynamic crossover rate. This is chosen to be the chromosome size. As the chromosome gets larger we assume that it is less likely to reproduce.

Specified by:

calculateCurrentRate in interface IUniversalRateCalculator

Returns:

calculated divisor of crossover rate

Since:

2.0

toBePermutated

public boolean toBePermutated()

Determines whether crossover is to be carried out for a given population.

Specified by:

toBePermutated in interface IUniversalRateCalculator

Returns:

true The DefaultCrossoverRateCalculator always returns a finite rate.

Since:

2.0
