A Novel Disruption Operator in Particle Swarm Optimization

Article Preview

Abstract:

Particle Swarm Optimization (PSO) has attracted many researchers attention to solve variant benchmark and real-world optimization problems because of its simplicity, effective performance and fast convergence. However, it suffers from premature convergence because of quickly losing diversity. To enhance its performance, this paper proposes a novel disruption strategy, originating from astrophysics, to shift the abilities between exploration and exploitation. The proposed Disruption PSO (DPSO) has been evaluated on a set of nonlinear benchmark functions and compared with other improved PSO. Comparison results confirm high performance of DPSO in solving various nonlinear functions.
