New Method of Continuous Function Optimization-Ant Colony Algorithm

To solve continuous function optimization problems, a new stochastic search algorithm based on ant swarm intelligence is introduced . This algorithm needn't continuous evaluation of derivatives for the object function and it can conquer the shortcomings which classic algorithms are apt to fall into the local optimum. At the same time, in order to reduce the number of function evaluations required for convergence, the basic CACO algorithm is improved. The improved algorithm has been tested for variety of different benchmark test functions, and it can handle these optimization problems very well. Furthermore, genetic algorithm is illustrated to optimize the parameters related to the ant colony algorithm, so that the convergence speed of the ant colony algorithm is improved.
