simulated annealing

Statistics

A method for maximizing a function that permits an algorithm to choose apparently suboptimal routes, but with decreasing probability as the number of iterations increases (see iterative algorithm). The initially fluid choice of values becomes increasingly set as the algorithm progresses. The object is to reduce the chance of ending at a local maximum.

Computer

A powerful enhancement for hill climbing search in which there is a small probability that random moves will be allowed in directions different from the preferred up-hill direction. This permits occasional moves to occur which can allow the hill climber to escape from local maxima. Initially large moves are allowed but a ‘cooling’ regime continuously lowers the probability of random directions during the search and thus the solution tends to settle on the best local maximum.

Internet

A technique used in data mining to select an optimal set of data from a large space of solutions. The term comes from the fact that the techniques uses a process similar to that found when metals are cooled slowly.
