Studies on Three Modern Optimization Algorithms

Modern optimization includes genetic algorithm （GA）, ant colony algorithm （ACO）, particle swarm algorithm optimization （PSO）, fish-swarm algorithm and simulated annealing algorithm （SA） and so on. They are mainly applied to solve some difficult optimization problems. The paper mainly makes a comparative study of the optimization performance of GA, PSO and SA. First the basic principles of the three algorithms are introduced, and the characteristics and advantages of these algorithms are understood. At last, the three algorithms are used for typical functions calculation, and comparative analysis is made to the results. And the future research directions are put forward.
