Updaters
type Updater a = UpdaterContext a => Random (Vector Weight) Source #
Evaluate the new velocity of a particle using the global best and iteration number.
randomVelocity :: UpdaterContext a => Random (Vector Weight) Source #
Produce random velocity with components up to given limit.
globalGuideDirection :: UpdaterContext a => Vector Weight Source #
Produce random velocity in the direction of the current global best, covering a random portion of the distance between them up to the given limit.
localGuideDirection :: UpdaterContext a => Vector Weight Source #
Produce random velocity in the direction of the current local best, covering a random portion of the distance between them up to the given limit.
previousVelocity :: UpdaterContext a => Vector Weight Source #
Just repeats the previous particle velocity.
Data structures
