Runtime analysis of binary PSO [PDF]

open access: yesProceedings of the 10th annual conference on Genetic and evolutionary computation, 2008
We investigate the runtime of the Binary Particle Swarm Optimization (PSO) algorithm introduced by Kennedy and Eberhart (1997). The Binary PSO maintains a global best solution and a swarm of particles. Each particle consists of a current position, an own best position and a velocity vector used in a probabilistic process to update the particle's ...
