Hybrid metaheuristics in combinatorial optimization: A survey

Abstract: Research in metaheuristics for combinatorial optimization problems has lately experienced a noteworthy shift towards the hybridization of metaheuristics with other techniques for optimization. At the same time, the focus of research has changed from being rather algorithm-oriented to being more problem-oriented.\ud Nowadays the focus is on solving the problem at hand in the best way possible, rather than\ud promoting a certain metaheuristic. This has led to an enormously fruitful cross-fertilization of differe… Show more

“…One reason of this historical links, let us say specialization, could be the historic divorce between research communities developing some metaheuristics during the first two decades of their existence. Indeed, as stated by Blum et al (2011), "during the first two decades of research on metaheuristics, different research communities working on metaheuristic techniques coexisted without much interaction, neither among themselves nor with operations research community." As pointed out by Matthews (2001), simulated annealing and taboo search, both taking their roots in the neighborhood search method, are two popular methods in forest management.…”

“…The specific characteristics of the latter, e.g., the number of objectives and constraints could also guide this choice. Many literature reviews describing the historical development of metaheuristics and their basic concepts have been published (Bahesti and Shamsuddin 2013;Blum et al 2011;Boussaïd et al 2013;Jarraya and Bouri 2012;Jones et al 2002;Madhuri and Deep 2009). We refer interested readers to the recent review of metaheuristics (Boussaïd et al 2013).…”

“…It is nowadays widely known that Ant Colony Optimization (ACO) is a metaheuristic inspired by the behaviour of ants looking for food, initially proposed by Dorigo and colleagues for combinatorial optimization and then extended and refined in many works (e.g., [22,23,19,24]ACO is essentially centered on the execution of a cycle where a number of feasible solutions are iteratively built, using information about solution construction executed in previous runs of the cycle. An ACO algorithm (ACO-alg) presents the general structure of Algorithm 1.…”

“…To repair an infeasible partial fixing of the variables z induced by a complete FOS or to improve an incumbent feasible solution, we rely on an MIP heuristic that operates a very large neighborhood search exactly, by formulating the search as a mixed integer linear program solved through an MIP solver [24]. Specifically, given a (feasible or infeasible) and possibly not complete fixingz of variables, we define the neighborhood N including all the feasible solutions of 3-ConFL-MILP that can be obtained by modifying at most n > 0 components ofz and leaving the remaining variables free to vary.…”
