A greedy algorithm arrives at a solution by making a sequence of choices, each of which simply looks the best at the moment. ▓ Dynamic Programming v.s. Greedy Approach 對於具有限制的最佳化問題,可以採用 “貪婪法則” 或 “動態規劃” 來設計演算法則。 Greedy Approach: 是一種階段性 (Stage) ...

用Kruskal算法求无向图 G 的最小生成树。 解法 Kruskal算法是一种贪心算法。初始时将图 G 的边集 E 按照权值,从小到大进行排序,并且生成树。从最小权值的边开始,依次考虑每一条边,对于边 e_i 来说,若将它加入生成树集合 S 中, e_i 不会与 S 中已有的边形成环,那么选取边 e_i 作为生成树中的一条...
