Simulation of GA algorithm based on MATLAB

Abstract： Genetic algorithm is an algorithm imitation of biological evolution, it has been used in a lot of areas, and had a relatively wide range of applications, including robotics, automation, and mathematical problems of permutations issues.What genetic algorithm is applied to real life and to play it is different from the other algorithms advantage is a subject worthy of study.And this is mainly for a comparison test against various algorithms Genetic algorithms, various algorithms derived differences and advantages and disadvantages, as well as the parameters of each algorithm changes for the whole program and the final result of the impact of the algorithm genetic algorithm, then draw a table to get the most intuitive conclusion.

Genetic algorithms can be derived in a number of different categories of genetic algorithm based on different algorithms using basic operations. There are three basic operations are: selection, crossover and mutation.The derived algorithms, including basic genetic algorithm, the order of selection genetic algorithm, fitness function value calibration algorithm, big mutation genetic algorithm, double-cut point crossover genetic algorithm, adaptive genetic algorithm and adaptive genetic changeable ectopic algorithm.
