Task Scheduling with Improved Particle Swarm Optimization in Cloud Data Center

EasyChair Preprint no. 11312

11 pagesDate: November 17, 2023


This paper proposes an improved particle swarm optimization algorithm with simulated annealing (IPSO-SA) for the task scheduling problem of cloud data center. The algorithm uses Tent chaotic mapping to make the initial population more evenly distributed. Secondly, nonlinear adaptive inertia weights is incorporated to adjust optimization seeking capabilities of particles in different iteration periods. Finally, the Metropolis criterion in SA is used to generate perturbed particles, combined with an modified equation for updating particles to avoid premature particle convergence. Comparative experimental results show that the IPSO-SA algorithm improves 13.8% in convergence accuracy over the standard PSO algorithm. The respective improvements over the other two modified PSO are 15.2% and 9.1%.
