We may recall here that very similar abiotic environments have given rise to a very dissimilar flora . 这里我们可以回想起这样一种情况,即十分相似的非生物环境产生了十分不相似的植物区系。

Negative assorative mating occurs when dissimilar phenotypes breed together , leading to outbreeding 反向选型交配则发生在不相似的表型在一起生育时,可以导致异系交配。
In this algorithm , the ants move objects in the 2d board frequently , by which the objects can be compared with each other . by this way we can place the similar objects together , remove the dissimilar objects away , and get the clusters that we are needed . then we use k - means algorithm using the initial partition provided by ants , which can converge faster 在该算法中,蚂蚁在二维网格空间中不断的搬运数据对象,比较它们之间的相似性,把相似性大的数据对象放到一起,不相似的数据对象移开,达到了聚类分析的结果,并把聚类结果作为k - means的初始聚类中心,用k - means算法对数据进一步进行聚类分析,加快算法的收敛性。
