A large number of real-world planning problems called combinatorial optimization problems share the following properties: They are optimiza- tion problems, are easy to state, and have a nite but usually very large number of feasible solutions.

这是一个构造最小生成树的Prim算法，是属于贪心算法的范畴。设G=(V,E)是连同带权图，V={1，2，3，...，n}。构造G的最小生成树。-This is a structure of Prim minimum spanning tree algorithm is a greedy algorithm category. Set G = (V, E) is, together with the weighted graph, V = (1,2,3 ,..., n). G of the min
