java.lang.Object org.moeaframework.core.operator.TwoPointCrossover
public class TwoPointCrossover
Twopoint crossover. Two crossover points are selected and all decision variables between the two points are swapped between the two parents. The two children resulting from this swapping are returned.
Constructor Summary  

TwoPointCrossover(double probability)
Constructs a twopoint crossover operator with the specified probability of applying this operator to solutions. 
Method Summary  

Solution[] 
evolve(Solution[] parents)
Evolves one or more parent solutions (specified by getArity ) and
produces one or more child solutions. 
int 
getArity()
Returns the number of solutions that must be supplied to the evolve method. 
double 
getProbability()
Returns the probability of applying this operator to solutions.
