Detailed Description

template<class POT>
class eoRingTopology< POT >

Static ring topology for particle swarm optimization.

The neighborhoods are built using a ring based on each particle's indice and do not change for all the time steps. Only the best particle in each neighborhood is potentially updated thanks to the "updateNeighborhood" method.

Examples:

t-eoRingTopology.cpp.

Definition at line 45 of file eoRingTopology.h.

template<class POT >

void eoRingTopology< POT >::setup

(

const eoPop< POT > &

_pop

)

[inline, virtual]

Builds the neighborhoods using a ring strategy based on the particle indices.

Also initializes the best particle of each neighborhood.

Parameters:

_pop	- The population used to build the only neighborhood.

Returns:

Implements eoTopology< POT >.

unsigned eoRingTopology< POT >::retrieveNeighborhoodByIndice

(

unsigned

_indice

)

[inline]

Retrieves the neighboorhood of a particle.

Returns:

_indice - The particle indice (in the population)

void eoRingTopology< POT >::updateNeighborhood	(	POT &	_po,
		unsigned	_indice
	)		[inline, virtual]

Updates the best fitness of the given particle and potentially replaces the local best the given particle it's better.

Parameters:

_po	- The particle to update
_indice	- The indice of the given particle in the population

Implements eoTopology< POT >.

POT& eoRingTopology< POT >::best

(

unsigned

_indice

)

[inline, virtual]

Returns the best particle belonging to the neighborhood of the given particle.

Parameters:

_indice

- The indice of a particle in the population

Returns:
