一种基于模糊聚类的构造进化树方法

各种生物之间的进化史可以通过构建进化树来讨论，因此进化树的研究成了一个研究热点。提出将利用DNA序列的4D表示所得相似矩阵视为模糊矩阵，再利用最大树法来构建进化树的方法。该方法不需要多序列比对，计算简单，实验验证了该方法的有效性。

Method of constructing phylogenetic tree based on fuzzy clustering

The evolutionary history of various species can be disscussed by constructing the phylogeny trees. Therefore, many scientists focus on the research of the phylogeny trees. In this paper, the authors used the similarity matrix computed by 4D representation of DNA sequence and regarded it as a fuzzy matrix, then used the maximal tree method to construct the phylogeny tree. This method need not sequence alignment and the computation is simple. The experiments demonstrate its validity.
