PSO (Particle Swarm Optimization) Example Step-by-Step

 Particle swarm optimization (PSO)

What is meant by PSO?

PSO is a computational method that Optimizes a problem. It is a Population-based stochastic search algorithm. PSO is inspired by the Social Behavior of Birds flocking. n Particle Swarm Optimization the solution of the problem is represented using Particles. [Flocking birds are replaced with particles for algorithm simplicity]. Objective Function is used for the performance evaluation for each particle / agent in the current population. PSO solved problems by having a Population (called Swarms) of Candidate Solutions (Particles). Local and global optimal solutions are used to update particle position in each iteration.

How PSO will optimize?

By Improving a Candidate Solution.

How PSO Solve Problems?
PSO solved problems by having a Population (called Swarms) of Candidate Solutions (Particles). The population of Candidate Solutions (i.e., Particles).

What is Search Space in PSO?

It is the range in which the algorithm computes the optimal control variable. When any optimal control value of any particle exceeds the searching space, the value will be reinitialized. 

PSO Disadvantage: PSO algorithm do not guarantee an optimal solution is ever found

What is the PSO fitness value?
Fitness Function is used in Metaheuristic Algorithms for OPTIMIZATION.
