基于LF算法改进的动态蚁群聚类算法
首发时间:2012-04-06
摘要:蚁群聚类算法是一种基于蚁群群体行为模型的聚类分析算法。其中,LF算法是基于蚁群分类幼蚁模型的标准蚁群聚类算法。本文改进了LF算法并提出IDLF算法。IDLF算法的改进主要包括:提出三种新的移动规则,增强蚂蚁移动的目的性;改进算法的结束条件,使算法能够根据实际聚类情况自动结束;动态调整蚂蚁的相关参数,增强算法的自适应性;提出了对蚂蚁长期空载或者负载情况的解决方案。实验结果证明,IDLF算法聚类的效率和精度都要高于LF算法。

An Improved Dynamic Ant Colony Algorithm Based on LF Algorithm
Abstract:The ant colony algorithm which is based on the group behavior of the ant colony is one of the cluster analysis algorithms. Among these algorithms, LF algorithm is the standard ant colony algorithm based on the model that ant colony sort the young ants. This paper improves the LF algorithm and proposes IDLF algorithm. It mainly contains the following improvements of the IDLF algorithm: proposing three kinds of new moving rules to enhance the moving purpose of the ants; improving the termination condition of LF algorithm so that the algorithm can terminate automatically according to the actual clustering; adjusting the relevant parameters dynamically to enhance the self-adaptability of the algorithm; proposing the solution to deal with the situation of long-term loading or unloading actions of the ants. The results of the experiments demonstrate that the clustering efficiency and accuracy of IDLF algorithm are better than those of LF algorithm .
