An overview of particle swarm optimizationParticle swarm optimization (PSO) is a kind of swarm intelligence algorithm, which is designed by simulating the predation behavior of bird swarm. Assuming that there is only one piece of food in the area (i.e. the optimal solution as described in the usual optimization problem
First, IntroductionHello everyone, there is a period of time not updated blog, recently the body is not very comfortable ha, today began to continue even more. To get to the chase, this is about "particle swarm optimization". The algorithm was inspired by two scientists in 1995, based on the research of bird predation. OK, let's get started.second, bird predation behaviormother Bird has 7 baby birds, one day, mother bird let the birds go to find worms
