The second method is called crossover , and entails choosing two individuals to swap segments of their code, producing artificial "offspring" that are combinations of their parents. In Algorithm 1, the GA mainly includes the phases of initialization, selection, crossover,. Solutions from one population are taken and used to form a new population, as there is a chance that the new population will be better than the old one. Building an AI algorithm for the Tic-Tac-Toe challenge. However, binary character set is preferred because it yield the largest number of schemata for any given parameter resolution, thereby enhancing the implicit parallelism of genetic searches. The obtained performance is similar as Dijkstra's algorithm. Genetic Algorithms have wide varieties of applications spread over the field of computing.
