Swarm particle
In computational science, particle swarm optimization (PSO) is a computational method that optimizes a problem by iteratively trying to improve a candidate solution with regard to a given measure of quality. It solves a problem by having a population of candidate solutions, here dubbed particles, and … Prikaži več A basic variant of the PSO algorithm works by having a population (called a swarm) of candidate solutions (called particles). These particles are moved around in the search-space according to a few simple formulae. The … Prikaži več The choice of PSO parameters can have a large impact on optimization performance. Selecting PSO parameters that yield good performance has therefore been the subject of much … Prikaži več There are several schools of thought as to why and how the PSO algorithm can perform optimization. A common belief amongst researchers is that the swarm … Prikaži več • Particle Swarm Central is a repository for information on PSO. Several source codes are freely available. • A brief video of particle swarms optimizing … Prikaži več The topology of the swarm defines the subset of particles with which each particle can exchange information. The basic version of the … Prikaži več Numerous variants of even a basic PSO algorithm are possible. For example, there are different ways to initialize the particles and velocities (e.g. … Prikaži več • Artificial bee colony algorithm • Bees algorithm • Derivative-free optimization Prikaži več

As the name suggests, the Swarm algorithm solves a problem by simulating the movement of a group of objects in the space of possible solutions. In the multi-swarm version, there are multiple swarms instead of just one. The basic component of a swarm is called a particle.
