Detailed Description

Steady state algorithm with tournament elimination operator

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

The algorithm flow:

  single generation {
   repeat(deme size times) {
    randomly add <nTournament_> individuals to the tournament;
    select the worst one in the tournament;
    randomly select two parents from remaining ones in the tournament;
    replace the worst with crossover child;
    perform mutation on child;
   }
  }

Member Function Documentation

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

Perform a single generation on a single deme.

Must be implemented by a specific algorithm class

this algorithm: one _generation_ is 'deme->size()' _iterations_

Implements Algorithm.

Definition at line 46 of file AlgSteadyStateTournament.cpp.

bool SteadyStateTournament::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.

Definition at line 27 of file AlgSteadyStateTournament.cpp.

void SteadyStateTournament::registerParameters ( StateP   )  [virtual]

Register algorithm's parameters (if any).

Called by the system before algorithm initialization (Algorithm::initialize)

Reimplemented from Algorithm.
