This is a chronologically ordered list of metaphor-based metaheuristics and swarm intelligence algorithms.

List of metaphor-based metaheuristics - Wikipedia

Simulated annealing SA is a probabilistic technique inspired by a heat phd thesis genetic algorithms wiki method in metallurgy. It is often used when the search space is discrete e. For problems where finding the phd thesis genetic global optimum is less important than finding an acceptable local optimum in a fixed amount of time, phd thesis genetic algorithms wiki annealing may be preferable to alternatives such as gradient descent.

Phd thesis genetic algorithms wiki annealing interprets slow cooling as a slow decrease in the probability of accepting worse solutions as it explores the solution space. Accepting worse solutions is a fundamental property of metaheuristics because algorithms wiki allows for a more extensive search for the optimal solution.

The ant colony optimization algorithm ACO is a probabilistic technique phd thesis genetic algorithms wiki solving computational problems which can be reduced to finding good paths through graphs. Initially source by Marco Dorigo in in his PhD thesis, [1] [2] the first algorithm was aiming to search for an optimal path in wiki phd thesis genetic algorithms wiki, based on the behavior article source ants seeking a path between their colony and a source of food.

The original idea has since diversified to solve a algorithms wiki class of numerical problems, and as a result, several problems have emerged, drawing on various aspects of the behavior of ants.

From custom paper writing help pdf broader perspective, ACO performs a model-based search [3] and shares some similarities with Estimation of Distribution Algorithms. Particle swarm optimization PSO is a computational method that optimizes a problem by iteratively trying to improve a candidate solution with regard to a given measure of quality.

It solves a problem by having a population of candidate solutions, here dubbed particlesand moving these particles around in the search-space according to simple mathematical formulae over the particle's phd thesis genetic algorithms wiki and velocity.

Each particle's movement is influenced by phd thesis genetic algorithms wiki local best known position, but is also guided toward the best known positions in the search-space, which are updated as better positions are found by other particles. This is expected to move the swarm toward the best solutions.

PSO phd thesis originally attributed to Phd thesis genetic algorithms wikiEberhart and Shi [4] [5] and was phd thesis genetic algorithms wiki intended for simulating social behaviour[6] phd thesis genetic algorithms wiki a stylized representation of the movement of organisms in a bird flock or fish school.

The algorithm was simplified and it was observed to be performing optimization.

List of genetic algorithm applications

The book by Kennedy and Eberhart [7] describes many philosophical aspects of Phd thesis genetic algorithms wiki and swarm intelligence. An extensive survey of PSO applications is made by Poli. Harmony search has algorithms wiki strongly criticized for being a special case phd thesis genetic algorithms wiki the well-established Evolution Strategies algorithm. Algorithms wiki Harmony search HS is a conservation essay simple yet very efficient evolutionary algorithm.

A new solution is generated by using all the solutions in the Harmony memory rather than just two as used in GA and if this new solution is better than the Worst solution in Harmony memory, the Worst solution gets replaced by this new solution.

All though HS is a relatively algorithms wiki meta heuristic algorithm, its effectiveness and advantages have been demonstrated in various applications like design of municipal water distribution networks, [13] structural design, [14] traffic routing, [15] load dispatch problem algorithms wiki electrical engineering, [16] multi objective phd thesis genetic algorithms wiki, [17] rostering problems, [18] clustering, [19] algorithms wiki and feature selection [20] [21] to name a few.

A detailed survey on applications of HS can be found in [22] and applications of HS in data mining can be found in. Artificial bee colony algorithm is a meta-heuristic homework online teachers introduced by Karaboga in[24] and simulates the foraging behaviour of honey bees. The ABC algorithm has three phases: In the employed bee and the onlooker bee phases, bees exploit the sources by local searches in the neighbourhood phd thesis genetic the solutions selected based phd thesis genetic algorithms deterministic selection in the employed bee phase and the probabilistic selection in the onlooker bee phase.
