Constructor Detail

DefaultMutationRateCalculator

public DefaultMutationRateCalculator()

Method Detail

calculateCurrentRate

public int calculateCurrentRate()

Calculates the mutation rate

Specified by:

calculateCurrentRate in interface IUniversalRateCalculator

Returns:

calculated divisor of mutation rate probability (dividend is 1)

Since:

1.1 (same functionality since earlier, but not encapsulated)

toBePermutated

public boolean toBePermutated()

Determines whether mutation is to be carried out. In this case the rate is the size of the chromosome. There is therefore a probability of 1/totalgenes that a particular gene mutates.

Specified by:

toBePermutated in interface IUniversalRateCalculator

Returns:

true if gene should be mutated.

Since:

2.0
