Description: 对于网络，其生成树中的边也带权，将生成树各边的权值总和称为生成树的权，并将权值最小的生成树称为最小生成树（Minimun Spanning Tree），简称为MST。
Prim算法的基本思想是：
(1) 在图G=(V, E) （V表示顶点 ，E表示边）中，从集合V中任取一个顶点（例如取顶点v0）放入集合 U中，这时 U={v0}，集合T(E)为空。
(2) 从v0出发寻找与U中顶点相邻（另一顶点在V中）权值最小的边的另一顶点v1，并使v1加入U。即U={v0,v1 }，同时将该边加入集合T(E)中。
(3) 重复(2)，直到U = V为止。

Description: 算法特点：该算法的特点是当前形成的集合T始终是一棵树。将T中U和TE分别看作红点和红边集，V-U看作蓝点集。算法的每一步均是在连接红、蓝点集的紫边中选择一条轻边扩充进T中。MST性质保证了此边是安全的。T从任意的根r开始，并逐渐生长直至U=V，即T包含了 C中所有的顶点为止。MST性质确保此时的T是G的一棵MST。因为每次添加的边是使树中的权尽可能小，因此这是一种"贪心"的策略。
-Algorithm characteristics: the algorithm is characterized by the formation of the current set of T is always a tree. The T, U and TE were seen as red dots and red edge set, VU as a blue dot set. Every step of the algorithm are connecting the red, blue, choose a set of purple fringing to expand into the T in the light side. The nature side of MST to ensure that this is safe. T starting from any root r, and gradually grow up to U = V, ie T contains all the vertices of C so far. MST to ensure that this time the nature of the tree T is a G MST. Because each side is to add the right tree as small as possible, so this is a " greedy" strategy.
