Abstract

The invention discloses a multi-objective cloud workflow scheduling method based on a wealth-poor optimization algorithm. By applying the wealth-poor optimization algorithm to discrete optimization problems, a new solution path is provided for multi-objective cloud workflow scheduling. A multi-objective optimization framework for multiple populations using two populations Ψ T and Ψ C , respectively optimize the maximum completion time makespan and execution cost cost of the workflow, that is, for Ψ T and Ψ C The individuals in the system use the rich-poor optimization algorithm and focus on their respective optimization objectives for updating, so as to fully optimize the two objectives at the same time and improve the efficiency of the iterative search of the algorithm.

Description
