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

Perform a single generation on a single deme.

Must be implemented by a specific algorithm class

Implements Algorithm.

Definition at line 58 of file AlgDifferentialEvolution.cpp.

bool DifferentialEvolution::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 31 of file AlgDifferentialEvolution.cpp.

void DifferentialEvolution::registerParameters ( StateP   )  [virtual]

Register algorithm's parameters (if any).

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

Reimplemented from Algorithm.
