In computer science and operations research, a genetic algorithm (GA) is a metaheuristic inspired by the process of natural selection that belongs to the larger class of evolutionary algorithms (EA). Genetic algorithms are commonly used to generate high- quality solutions to optimization and search problems by relying on bio- inspired operators such as mutation, crossover and selection.

Opinion is divided over the importance of crossover versus mutation. There are many references in Fogel (2. Although crossover and mutation are known as the main genetic operators, it is possible to use other operators such as regrouping, colonization- extinction, or migration in genetic algorithms. A very small mutation rate may lead to genetic drift (which is non- ergodic in nature). A recombination rate that is too high may lead to premature convergence of the genetic algorithm.
Typically, when an algorithm is associated with processing information, data is read from an input source or device, written to an output sink or device, and/or stored for further processing. Stored data is regarded as part of the internal state of the entity performing the algorithm. In practice, the state is stored in a , but an algorithm requires the internal data only for specific operation sets called .
Clustering prediction for the ID-based clustering algorithm
No generally accepted definition of "algorithm" exists. We can, however, derive clues to the issues involved and an informal meaning of the word from the following quotation from Boolos and Jeffrey (1974, 1999):
and the Karatsuba algorithm can be applied to and in this form
So far, this discussion of the formalization of an algorithm has assumed the premises of . This is the most common conception, and it attempts to describe a task in discrete, 'mechanical' means. Unique to this conception of formalized algorithms is the , setting the value of a variable. It derives from the intuition of '' as a scratchpad. There is an example below of such an assignment.

Just as a child creates magnificent fortresses through the arrangement of simple blocks of wood, so does a genetic algorithm seek near optimal performance through the juxtaposition of short, low- order, high- performance schemata, or building blocks. Many estimation of distribution algorithms, for example, have been proposed in an attempt to provide an environment in which the hypothesis would hold.

This is actually problem classification in the strict sense. Some algorithms complete in linear time proportional to input size, and some do in exponential amount of time, and some never do. Some problems may have multiple algorithms, some problems may have no algorithms, and some problems have no known efficient algorithms. There are also mappings from some problems to other problems. So computer scientists found it is suitable to classify the problems rather than algorithms into equivalence classes based on the complexity.

Some countries allow algorithms to be when embodied in software or in hardware. Patents have long been a controversial issue (see, for example, the ). Some countries do not allow certain algorithms, such as cryptographic algorithms, to be from that country (see ).
