Metaheuristic Optimization - Scholarpedia
In computer science and mathematical optimizationa metaheuristic is a higher-level procedure or heuristic designed to find, generate, or select a heuristic partial search algorithm that may provide a sufficiently good solution to an optimization problemespecially with incomplete or imperfect information or limited computation capacity.
Metaheuristics may make relatively few assumptions about the optimization problem being solved and so may be usable for a variety of problems. Compared to optimization algorithms and iterative methodsmetaheuristics do ant colony optimization phd thesis guarantee that a globally optimal solution can be found on some class of problems.
Most literature on metaheuristics is experimental in nature, describing empirical results based on computer experiments with the algorithms.
But some formal theoretical results are also available, often on convergence and the possibility of finding the global optimum. While the field also features high-quality research, many of ant colony optimization phd thesis publications have been of poor quality; flaws include vagueness, lack of conceptual elaboration, poor experiments, and ignorance of previous literature.
These are properties that characterize most metaheuristics: [3]. There are a wide variety of metaheuristics [2] and a number of properties with respect to which to classify them. One approach is to characterize the type of search strategy. A well known local search algorithm is the hill climbing method which is used to find local optimums. However, hill climbing does not guarantee finding global optimum solutions. Many metaheuristic ideas were proposed to improve local search heuristic in order to find better solutions.
Such metaheuristics include simulated annealingtabu searchiterated local searchvariable neighborhood searchand GRASP. Other global search metaheuristic that are not local search-based are usually population-based metaheuristics. Such metaheuristics include ant colony optimizationevolutionary computationparticle swarm optimizationgenetic algorithmand rider optimization algorithm [9].
Another classification dimension is single solution vs population-based searches. Ant colony optimization[10] particle swarm optimization[6] social cognitive optimization are examples of this category.
A hybrid metaheuristic is one that combines a metaheuristic with other optimization approaches, such as algorithms from mathematical programmingconstraint programmingand machine learning. Both components of a hybrid metaheuristic may run concurrently and exchange information to guide the search.
On the other hand, Memetic algorithms [11] represent the synergy of evolutionary or any population-based approach with separate individual learning or local improvement procedures for problem search. An example of memetic algorithm is the use of a local search algorithm instead of a basic mutation operator in evolutionary algorithms. A parallel metaheuristic is one that uses the techniques of parallel programming to run multiple metaheuristic searches in parallel; these may range from simple distributed schemes to concurrent search runs that interact to improve the overall solution.
A very active area of research is the design of nature-inspired metaheuristics. Many recent metaheuristics, especially evolutionary computation-based algorithms, are inspired by natural systems.
Nature acts as a source of concepts, mechanisms and principles for designing of artificial computing systems to deal with complex computational problems. Such metaheuristics include simulated annealingevolutionary algorithmsant colony optimization and particle swarm optimization.
A large number of more recent metaphor-inspired metaheuristics have started to attract criticism in the research community for hiding their lack of novelty behind an elaborate metaphor. Metaheuristics are used for combinatorial optimization in which an optimal solution is sought over a ant colony optimization phd thesis search-space, ant colony optimization phd thesis. An example problem is the travelling salesman problem where the search-space of candidate solutions grows faster than exponentially as the size of the problem increases, which makes an exhaustive search for the optimal solution infeasible.
Additionally, multidimensional combinatorial problems, including most design problems in engineering [12] [13] [14] such as form-finding and behavior-finding, suffer from the curse of dimensionalitywhich also makes them infeasible for exhaustive search or analytical methods. Metaheuristics are also widely used for jobshop scheduling and job selection ant colony optimization phd thesis. Literature review on metaheuristic optimization, [19] suggested that it was Fred Glover who coined the word metaheuristics.
Many different metaheuristics are in existence and new variants are continually being proposed. Some of the most significant contributions to the field are:.
