- public class ReproductionPipeline
- extends BreedingPipeline
ReproductionPipeline is a BreedingPipeline which simply makes a copy
of the individuals it recieves from its source. If the source is another
BreedingPipeline, the individuals have already been cloned, so ReproductionPipeline
won't clone them again...unless you force it to do so by turning on the must-clone
parameter.
Typical Number of Individuals Produced Per produce(...) call
...as many as the child produces

Parameters
base.must-clone
bool = true or false (default) |
(do we always clone our individuals, or only clone if the individual hasn't already been cloned by our source? Typically you want false) |
Default Base
breed.reproduce

Method Summary |
Parameter |
defaultBase()
Returns the default base for this prototype. |
int |
numSources()
Returns the number of sources to this pipeline. |
int |
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. |
void |
setup(EvolutionState state,
Parameter base)
Sets up the BreedingPipeline. |

ReproductionPipeline
public ReproductionPipeline()
defaultBase
public Parameter defaultBase()
- Description copied from interface:
Prototype
- Returns the default base for this prototype.
This should generally be implemented by building off of the static base()
method on the DefaultsForm object for the prototype's package. This should
be callable during setup(...).
numSources
public int numSources()
- Description copied from class:
BreedingPipeline
- Returns the number of sources to this pipeline. Called during
BreedingPipeline's setup. Be sure to return a value > 0, or
DYNAMIC_SOURCES which indicates that setup should check the parameter
file for the parameter "num-sources" to make its determination.
- Overrides:
numSources
in class BreedingPipeline
setup
public void setup(EvolutionState state,
Parameter base)
- Description copied from class:
BreedingSource
- Sets up the BreedingPipeline. You can use state.output.error here
because the top-level caller promises to call exitIfErrors() after calling
setup. Note that probability might get modified again by
an external source if it doesn't normalize right.
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}.

throws java.lang.CloneNotSupportedException
- Description copied from class:
BreedingSource
- 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. max must be >= min, and min must be >= 1. For example, crossover
might typically produce two individuals, tournament selection might typically
produce a single individual, etc.
