Kruskal 算法基于贪心算法(Greedy Algorithm)的思想进行设计,其选择的贪心策略就是,每次都选择权重最小的但未形成环路的边加入到生成树中。其算法结构如下: 将所有的边按照权重非递减排序; 选择最小权重的边,判断是否其在当前的生成树中形成了一个环路。如果环路没有形成,则将该边加入树中,否则放弃。 重复步骤 2,...

The FAST algorithm works in two steps. In the first step, features are divided into clusters by using graph-theoretic clustering methods. In the second step, the most representative feature that is strongly related to target classes is selected from each cluster to form a subset of features....
克鲁斯卡尔算法是计算最小生成树的一种算法。和prim算法(上,中,下)按照节点进行查找的方法不一样,克鲁斯卡尔算法是按照具体的线段进行的。现在我们假设一个图有m个节点,n条边。首先,我们需要把m个节点看成m个独立的生成树,并且把n条边按照从小到大的数据进行排列。在n条边中,我们依次取出其中的每一条边,如果...
