Current-best Particle Swarm Optimization

Abstract

Particle Swarm Optimization (PSO) is a metaheuristic optimization method based on swarm intelligence. Due to its flexibility and ability to produce optimum performance, it is commonly used in various applications. While PSO has been used extensively to provide solutions to various complicated problems in engineering, it has also many deficiencies. Several improved PSO techniques have been proposed to compensate these deficiencies. However, there are still some scopes of improvement in its components. In this work, we have proposed an improvised PSO called Current-best Particle Swarm Optimization (CPSO) which introduces a new parameter called “cbest” that has been used in the social component of PSO to overcome the local minima issue. The suggested model, CPSO, has differentiate with the basic PSO method and the Iterative (ibest) PSO method using some optimization functions. The findings indicate that the recommended model outperforms the other models.
