Detailed Description

Generational algorithm with roulette wheel selection operator

This algorithm is genotype independent (it can be used with any Genotype).

The algorithm flow:

  single generation {
   select individuals to form the new generation (fitness proportional selection operator);
   create new generation (make copies);
   noCrx = (deme size) * <crxRate_> / 2;
   repeat(<noCrx> times) {
    randomly select two parents;
    perform crossover, _replace_ parents with their children;
   }
   perform mutation on new generation;
  }

bool RouletteWheel::advanceGeneration ( StateP  ,
DemeP   
) [virtual]

Perform a single generation on a single deme.

Must be implemented by a specific algorithm class

Implements Algorithm.

bool RouletteWheel::initialize ( StateP   )  [virtual]

Initialize the algorithm, read parameters from the system, do a sanity check.

Called by the system before the algorithm starts (Algorithm::advanceGeneration)

Reimplemented from Algorithm.
