“…Finally, in the work by Adhikari et al [14] the workload of cloud servers, makespan, resource usage, and stability were the goals of a workflow scheduling approach based on the firefly algorithm (FA). Concering the ILS algorithm, ILS has been used in many fields including, the travelling salesman problem [15], [16], vehicle routing problem [17], [18], flow-shop problem [19], [20], task scheduling on cloud computing [21], precedence-constraint task list scheduling [22], the parallel machine scheduling problems [23], and the quadratic assignment problem [24]. Several enhancements were proposed over time including, using clusters and a modified multi-restart [15], using multi types of neighborhoods moves [17], ILS memory-based [18], use of a biased-randomized [20], [25], and hybrid with other metaheuristics algorithms [21], [22].…”
