Genetic Algorithms Have Been Applied In Science, Engineering, Business and Social Sciences. Number of Scientists Has Already Solved Many Engineering Problems Using Genetic Algorithms. Ga Concepts Can Be Applied to the Engineering Problem Such As Optimization of Gas Pipeline Systems. Another Important Current Area Is Structure Optimization .The New Population Is Used In the Next Iteration of the Algorithm. the Algorithm Terminates When Either a Maximum Number of Generations Has Been Produced, or a Satisfactory Fitness Level Has Been Reached For the Population. Ga Is Also Used In Medical Imaging System. the Ga Is Used to Perform Image Registration As a Part of Larger Digital Subtraction Angiographies. It Can Be Found That Genetic Algorithm Can Be Used Over a Wide Range of Applications.
