/** eoPopEvalFunc: This abstract class is for GLOBAL evaluators
|
|
* of a population after variation.
|
|
* It takes 2 populations (typically the parents and the offspring)
|
|
* and is suppposed to evaluate them alltogether
|
|
*
|
|
* Basic use: apply an embedded eoEvalFunc to the offspring
|
|
*
|
|
* Time-varying fitness: apply the embedded eoEvalFunc to both
|
|
* offspring and parents
|
|
*
|
|
* Advanced uses: Co-evolution or "parisian" approach, or ...
|
|
*
|
|
* Basic parallelization (synchronous standard evolution engine):
|
|
* call the slaves and wait for the results
|
