public class MultiBreedingPipeline extends BreedingPipeline
Typical Number of Individuals Produced Per produce(...) call
If by base.generate-max is true, then always the maximum
number of the typical numbers of any child source. If false, then varies
depending on the child source picked.
Number of Sources
Dynamic. As many as the user specifies.
Parameters
base.generate-max bool = true (default) or false |
(Each time produce(...) is called, should the MultiBreedingPipeline force all its sources to produce exactly the same number of individuals as the largest typical number of individuals produced by any source in the group?) |
Default Base

defaultBase()
Returns the default base for this prototype.

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

produce(int min,

int subpopulation,
java.util.ArrayList<Individual> inds,
EvolutionState state,
int thread,
java.util.HashMap<java.lang.String,java.lang.Object> misc)
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.

BreedingSource
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}.
