Solving a Video-Server Load Re-Balancing Problem by Mixed Integer Programming and Hybrid Variable Nible the overall network load should be balanced among the available servers. We consider a problem formulation based on an estimation of the expected number of requests per movie during the period of highest user interest. Apart from load balancing our formulation also deals with the minimization o

Effective Hybrid Stochastic Local Search Algorithms for Biobjective Permutation Flowshop Schedulingblems. In particular, this paper tackles the three pairwise combinations of the objectives (i) makespan, (ii) the sum of the completion times of the jobs, and (iii) the weighted total tardiness of all jobs. The proposed algorithms are combinations of two local search methods: two-phase local search

Matheuristics: Optimization, Simulation and Control,s the exploitation in some part of the algorithms of features derived from the mathematical model of the problems of interest, thus the definition “model-based metaheuristics” appearing in the title of some events of the conference series dedicated to matheuristics [1]. The topic has attracted the i
