Genetic Algorithms• Genetic algorithms are a part of evolutionary computing,
which is a rapidly growing area of artificial intelligence.
• Genetic algorithms are inspired by Darwin's theory about evolution.
• It is an intelligent random search technique used to solve optimization problem
• Although randomized but GA’s exploit historical information to direct the search into the region of better performance within the search space.
