大顶堆实现一个优先队列。对于队列的操作应该至少支持下列几种指令:
Void enqueue[int ObjectID, int Priority]
Int dequeue[]
Void changeweight[int ObjectID, int newPriority]
-Large Top Heap realize a priority queue. For the operation of the queue should be at least support

Johson算法是目前最高效的在无负环可带负权重的网络中求所有点对最短路径的算法. Johson算法是Bellman-Ford算法, Reweighting(重赋权重)和Dijkstra算法的大综合. 对每个顶点运用Dijkstra算法的时间开销决定了Johnson算法的时间开销. 每次Dijkstra算法(d堆PFS实现)的时间开销是O( E * lgd(V) ). 其中E为边数, V为顶点数, d为采用d路堆实现优先队列ADT. 所以, 此种情况下Johnson算法的时间复杂度是O( V *

设图的顶点大于1个,不超过30个,每个顶点用一个编号表示(如果一个图有n个顶点,则它们的编号分别为0, 1, 2, 3, …, n-1)。
此题为求有向网中顶点间最短路径问题,可建立以票价为权的邻接矩阵,用Dijkstra算法求最短路径长度。
Dijkstra算法中有一个辅助向量D,表示当前所找到的从源点到其它点的最短路径长度。因为每次都要在D中找最小值,为提高性能,用最小值堆的优先队列存储D值。
