Optimization problems[ edit ] In a genetic algorithm, a population of candidate solutions called individuals, creatures, or phenotypes to an optimization problem is evolved toward better solutions. Each candidate solution has a set of properties its chromosomes or genotype which can be mutated and altered; traditionally, solutions are represented in binary as strings of 0s and 1s, but other encodings are also possible. In each generation, the fitness of every individual in the population is evaluated; the fitness is usually the value of the objective function in the optimization problem being solved.

The evolutionary process takes place during the reproduction stage. There exists a large number of reproductive mechanisms in Nature. Most common ones are mutation that causes the chromosomes of offspring to be different to those of the parents and recombination that combines the chromosomes of the parents to produce the offspring.
Based upon the features above, the three mentioned models of evolutionary computing were independently and almost simultaneously developed.
An Evolutionary Algorithm EA is an iterative and stochastic process that operates on a set of individuals population. Each individual represents a potential solution to the problem being solved.
Initially, the population is randomly generated perhaps with the help of a construction heuristic. Every individual in the population is assigned, by means of a? This value is the quantitative information the algorithm uses to guide the search.
Among the evolutionary techniques, the genetic algorithms GAs are the most extended group of methods representing the application of evolutionary tools. They rely on the use of a selection, crossover and mutation operators.
Replacement is usually by generations of new individuals. Intuitively a GA proceeds by creating successive generations of better and better individuals by applying very simple operations. The search is only guided by the? This value is used to rank individuals depending on their relative suitability for the problem being v vi Preface solved.
The problem is the? The location of this kind of techniques with respect to other deterministic and non-deterministic procedures is shown in the following tree. Combinations of EAs with Hill-Climbing algorithms are very powerful.
Genetic algorithms intensively using such local search mechanism are termed Memetic Algorithms. Also parallel models increase the extension and quality of the search. The EAs exploration compares quite well against the rest of search techniques for a similar search effort.

Researches on GAs in alife give illustrative examples in which the genetic algorithm is used to study how learning and evolution interact, and to model ecosystems, immune system, cognitive systems, and social systems.
