Genetic Algorithms(GAs) are adaptive heuristic search algorithms that belong to the larger part of evolutionary algorithms. Genetic algorithms are based on the ideas of natural selection and genetics Genetic algorithms are randomized search algorithms that have been developed in an effort to imitate the mechanics of natural selection and natural genetics. Genetic algorithms operate on string structures, like biological structures, which are evolving in time according to the rule of survival of the fittest by using a randomized yet structured information exchange The genetic algorithm is one such optimization algorithm built based on the natural evolutionary process of our nature. The idea of Natural Selection and Genetic Inheritance is used here. Unlike other algorithms, it uses guided random search, i.e., finding the optimal solution by starting with a random initial cost function and then searching only in the space with the least cost (in the guided direction) Genetic algorithms are a type of optimization algorithm, meaning they are used to nd the optimal solution(s) to a given computational problem that maximizes or minimizes a particular function A genetic algorithm is a search heuristic that is inspired by Charles Darwin's theory of natural evolution. This algorithm reflects the process of natural selection where the fittest individuals are selected for reproduction in order to produce offspring of the next generation

Genetic algorithms (GAs) are inspired by natural selection, as put forth by Charles Darwin. The idea is that over generations, the heritable traits of a population change because of mutation and the concept of survival of the fittest. Similar to natural selection, GAs iterate over multiple generations to evolve a population Genetic Algorithm. Genetic algorithm is the perfect solution to solve these kind of problems.
