public class UniquePipeline extends BreedingPipeline
Typical Number of Individuals Produced Per produce(...) call
...as many as the child produces
Number of Sources
1
Parameters
base.generate-max bool = true or false (default) |
(do we always generate the maximum number of possible individuals, or at least the minimum number?) |
base.duplicate-retries int >= 0 |
(number of times we try to find a duplicate individual before giving up and just filling the remainder with non-duplicate individuals) |

Modifier and Type | Method and Description |

java.lang.Object |
clone()
Creates a new individual cloned from a prototype,
and suitable to begin use in its own evolutionary
context.
|
Parameter |
defaultBase()
Returns the default base for this prototype.
|
int |
numSources()
Returns the number of sources to this pipeline.
|
void |
prepareToProduce(EvolutionState state,
int subpopulation,
int thread)
Called before produce(...), usually once a generation, or maybe only
once if you're doing steady-state evolution, to let the breeding source
"warm up" prior to producing.
|
int |
produce(int min,
int max,
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.
|
void |
setup(EvolutionState state,
Parameter base)
Sets up the BreedingPipeline.

Prototype
Typically this should be a full "deep" clone. However, you may share certain elements with other objects rather than clone hem, depending on the situation:

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}.
