Correction to: Adaptive Computational Solutions to Energy Efficiency in Cloud Computing Environment Using VM Consolidation

Virtual machine consolidation describes the process of reallocation of virtual machines (VMs) on a set of target servers. It can be formulated as a mixed integer linear programming problem which is proven to be an NP-hard problem. In this paper, we propose a kernel search (KS) heuristic algorithm based on hard variable fixing to quickly obtain a high-quality solution for large-scale virtual machine consolidation problems (VMCPs). Since variable fixing strategies in existing KS works may make VMCP infeasible, our proposed KS algorithm employs a more efficient strategy to choose a set of fixed variables according to the corresponding reduced cost. Numerical results on VMCP instances demonstrate that our proposed KS algorithm significantly outperforms the state-of-the-art mixed integer linear programming solver in terms of CPU time, and our proposed strategy of variable fixing significantly improves the efficiency of the KS algorithm as well as the degradation of solution quality can be negligible.
