Constructor Detail

UniformCrossover

public UniformCrossover(double probability)
Constructs a uniform crossover operator with the specified probability an index is swapped between two solutions.

Parameters:
probability - the probability an index is swapped between two solutions
Method Detail

getProbability

public double getProbability()
Returns the probability an index is swapped between two solutions.

Returns:
the probability an index is swapped between two solutions

evolve

public Solution[] evolve(Solution[] parents)
Description copied from interface: Variation
Evolves one or more parent solutions (specified by getArity) and produces one or more child solutions. By contract, the parents must not be modified. The copy constructor should be used to create copies of the parents with these copies subsequently modified.

Specified by:
evolve in interface Variation
Parameters:
parents - the array of parent solutions
Returns:
an array of child solutions

getArity

public int getArity()
Description copied from interface: Variation
Returns the number of solutions that must be supplied to the evolve method.

Specified by:
getArity in interface Variation
Returns:
the number of solutions that must be supplied to the evolve method
