This paper presents a new diversity guided Particle Swarm Optimization algorithm (PSO) named Beta Mutation PSO or BMPSO for solving global optimization problems. The BMPSO algorithm makes use of an evolutionary programming based mutation operator to maintain the level of diversity in the swarm population, thereby maintaining a good balance between the exploration and exploitation phenomena and preventing premature convergence. Beta distribution is used to perform the mutation in the proposed

The numerical results show that the proposed algorithm outperforms the basic PSO algorithm in all the test cases taken in this study.
