public class IntermediateCrossover<G extends NumericGene<?,G>,C extends Comparable<? super C>> extends Crossover<G,C>
Points outside of the allowed numeric range are rejected and a new points are
generated, until they lie in the valid range. The strategy on how
out-of-range points are handled, is the difference to the very similar
LineCrossover.

IntermediateCrossover()
Creates a new intermediate-crossover with default recombination
probability (
Alterer.DEFAULT_ALTER_PROBABILITY) and a p value
of zero, which restricts the recombined chromosomes within the hypercube
of the selected chromosomes (vectors). |
IntermediateCrossover(double probability)
Creates a new intermediate-crossover with the given recombination
probability.
|
IntermediateCrossover(double probability,
double p)
Creates a new intermediate-crossover with the given recombination
probability and the line-scaling factor p.

When the value for p is greater then 0, the crossover point generation must be repeated until the points lie within the allowed range. Values greater then 10 are usually not recommended, since this leads to unnecessary crossover point generation.
probability - the recombination probability.p - defines the possible location of the recombined chromosomes. If
p = 0 then the children will be located along the line
within the hypercube between the two points. If p > 0
then the children may be located anywhere on the line, even
somewhat outside of the hypercube.IllegalArgumentException - if the probability is not in the
valid range of [0, 1] or if p is smaller then zeropublic IntermediateCrossover(double probability)
