Detailed Description

template<class POT>
class eoLinearTopology< POT >

One of the local best strategies for particle swarm optimization.

Each particle has a fixed number of neighbours, ans the neighborhood is social. The topology is never modified during the flight.

Constructor & Destructor Documentation

template<class POT>

eoLinearTopology< POT >::eoLinearTopology

(

unsigned

_neighborhoodSize

)

[inline]

Build the topology made of _neighborhoodSize neighborhoods.

Parameters:

_neighborhoods

- The size of each neighborhood.

Member Function Documentation

template<class POT>

void eoLinearTopology< POT >::setup

(

const eoPop< POT > &

_pop

)

[inline, virtual]

Build the neighborhoods contained in the topology.

Parameters:

_pop

- The population used to build the neighborhoods. If it remains several particle (because _pop.size()neighborhoodSize !=0), there are inserted in the last neighborhood. So it may be possible to have a bigger neighborhood.

Implements eoTopology< POT >.

template<class POT>

unsigned eoLinearTopology< POT >::retrieveNeighborhoodByIndice

(

unsigned

_indice

)

[inline]

Retrieve the neighboorhood of a particle.

Returns:

_indice - The particle indice (in the population)

template<class POT>

POT& eoLinearTopology< POT >::best

(

unsigned

_indice

)

[inline, virtual]

Return the best informative of a particle.

Could be itself.

Parameters:

_indice

- The indice of a particle in the population

Returns:

POT & - The best particle in the neighborhood of the particle whose indice is _indice
