问题描述(单资源)
Dijkstra(1965)年提出了一种能够避免死锁的调度方法,称为银行家算法。它的模型基于一个小城镇的银行家,描述如下:假定一个银行家拥有资金,数量为Ё,被N个可户共享。银行家对可户提出下列约束条件:
Ⅰ.每个客户必须预先说明自己所要求的最大资金量;
Ⅱ.每个客户每次提出部分资金量申请和获得分配;
Ⅲ.如果银行家满足了客户对资金的最大需求量,那么,客户在资金运作后,应在有限时间内全部归还银行。-problem descr iption (single-res

Dijstra算法
由Dijkstra提出的一种按路径长度递增序产生各顶点最短路径的算法。
(1)按路径长度递增序产生各顶点最短路径
若按长度递增的次序生成从源点s到其它顶点的最短路径,则当前正在生成的最短路径上除终点以外,其余顶点的最短路径均已生成(将源点的最短路径看作是已生成的源点到其自身的长度为0的路径)。-Dijstra by Dijkstra algorithm proposed by an incremental path length of the sequence

该问题为单元最短路经问题,求出一个有向图中两点之间权值最小的路径。 Dijkstra算法要求有向图中没有权值为负的边,有向图的信息由一个邻接表来表示,另外对每个顶点都设置一个属性d[v],描述从源点到v的最短路经上权值的上界。算法中设置一个顶点集合S,反复选择具有最短路经估计的顶点u∈V-S,并将u加入S中,算法中还用到了顶点的最小优先队列,排序关键字为顶点的d值。-The issue of the shortest path problem as a unit, find a directed

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。
