Detailed Description

Interface for running a genetic algorithm of which the genome fitnesses are calculated in a distributed way using MPI. Note that currently no load balancing is performed, each node will get approximately the same amount of genomes to calculate.

Member Function Documentation

bool mogal::MPIGeneticAlgorithm::runMPI	(	GAFactory &	factory,
		size_t	populationSize,
		const GeneticAlgorithmParams *	pParams = 0
	)

Start this function on the root node (rank 0) to start a distributed GA.

Parameters:

factory	The factory which should be used. This factory has to be initialized before this function is called.
populationSize	Size of the population.
pParams	Parameters for the genetic algorithm.

bool mogal::MPIGeneticAlgorithm::runMPIHelper

(

GAFactory &

factory

)

When the runMPI function is started on the root node, this function should be called on the helper nodes.

Parameters:

factory

The factory which should be used. This factory has to be initialized before this function is called. Note that this is not distributed using the MPI mechanism, you'll need to make sure yourself that each node has an initialized version of the factory when this function is called.
