public class CheckingPipeline extends BreedingPipeline
In some cases you may wish instead to produce individuals which are individually checked for validity, rather than together. The easiest way to do this is to add the CheckingPipeline as a child to a ForceBreedingPipeline which has been set with num-inds=1.
Typical Number of Individuals Produced Per produce(...) call
...as many as either child produces

defaultBase()
Returns the default base for this prototype.

numSources()
Returns the number of sources to this pipeline.

produce(int min,
int max,
int start,
int subpopulation,
Individual[] inds,
EvolutionState state,
int thread)
Produces n individuals from the given subpopulation
and puts them into inds[start...start+n-1],
where n = Min(Max(q,min),max), where q is the "typical" number of
individuals the BreedingSource produces in one shot, and returns
n.

The most common modification is to normalize it with some other set of probabilities, then set all of them up in increasing summation; this allows the use of the fast static BreedingSource-picking utility method, BreedingSource.pickRandom(...). In order to use this method, for example, if four breeding source probabilities are {0.3, 0.2, 0.1, 0.4}, then they should get normalized and summed by the outside owners as: {0.3, 0.5, 0.6, 1.0}.
