Orthogonal Methods Based Ant Colony Search for Solving Continuous Optimization Problems

计算机科学技术学报 , 2008,
Abstract: Research into ant colony algorithms for solving continuous optimization problems forms one of the most significant and promising areas in swarm computation. Although traditional ant algorithms are designed for combinatorial optimization, they have shown great potential in solving a wide range of optimization problems, including continuous optimization. Aimed at solving continuous problems effectively, this paper develops a novel ant algorithm termed “continuous orthogonal ant colony” (COAC), whose pheromone deposit mechanisms would enable ants to search for solutions collaboratively and effectively. By using the orthogonal design method, ants in the feasible domain can explore their chosen regions rapidly and efficiently. By implementing an “adaptive regional radius” method, the proposed algorithm can reduce the probability of being trapped in local optima and therefore enhance the global search capability and accuracy. An elitist strategy is also employed to reserve the most valuable points. The performance of the COAC is compared with two other ant algorithms for continuous optimization — API and CACO by testing seventeen functions in the continuous domain. The results demonstrate that the proposed COAC algorithm outperforms the others.

Abstract: Several popular approaches of simulated evolution have been developed separately. These approaches emphasize different facets of the natural evolutionary processes, respectively. One has recognized that the simulated evolution will benefit from the adequate combination between the approaches. This paper characterizes the primary difference among existing approaches as the difference between genetic link and behavioral link. A new model of simulated evolution, called FEBE(family eugenics based evolution), is proposed, which combines the genetic link with the behavioral link in light of the idea of family eugenics. In the FEBE model the orthogonal design technique is introduced into offspring's breeding inside a family so as to enhance the behavioral improvement of individuals. The FEBE model is applied to solve Goldberg's deceptive problem that is challenging to most evolutionary algorithms. The exciting experimental results are achieved.

Abstract: 本文针对一类带区间系数的非线性优化问题,提出了一种基于均匀搜索的遗传算法。首先,将原问题分解为两个确定的双层规划问题;其次,对两个双层问题的上层变量进行编码,通过求解相应的双层规划获得对个体的评估;最后,为避免近亲繁殖产生相似后代,采用相对距离控制杂交运算;并且引进摆动式正交杂交算子产生后代个体,使后代尽可能均匀产生。数据仿真结果表明,该算法是可行有效的。
For a class of nonlinear programming problems with interval coefficients, a genetic algorithm based on a uniformly searching scheme is proposed in this paper. Firstly, the original problem is transformed into two exact bilevel programs. Secondly, the upper level variables are encoded as individuals, and these individuals are evaluated by solving the bilevel programs. Finally, in order to avoid producing similar offspring by inbreeding, a relative distance is adopted to provide a threshold value for crossover. Also, an orthogonal crossover operator with point oscillating is provided to generate offspring as uniformly as possible. The experimental data indicate that this algorithm is feasible and effective.

Abstract:The cutting process parameters of dicing saw are difficult to get in actual production, an optimization method was thus proposed to establish the best cutting parameters based on genetic algorithm of Matlab. The scope of the cutting process parameters was selected by avoiding the natural frequency of every order, and the root mean square of the axis vibration was used as the evaluation index. The regression equation was established between parameters of vibration and cutting processes by regression orthogonal design. The best cutting parameters according to the minimum vibration were obtained by using the Matlab genetic algorithm to make iterative optimization for the regression equation. The optimization result was verified by experiments.
