Description: Floyd-Warshall算法描述 1)适用范围: a)APSP(All Pairs Shortest Paths) b)稠密图效果最佳 c)边权可正可负 2)算法描述: a)初始化:dis[u,v]=w[u,v] b)For k:=1 to n For i:=1 to n For j:=1 to n If dis[i,j]>dis[i,k]+dis[k,j] Then Dis[I,j]:=dis[I,k]+dis[k,j] c)算法结束:dis即为所有点对的最短路径矩阵 3)算法小结:此算法简单有效,由于三重循环结构紧凑,对于稠密图,效率要高于执行|V|次Dijkstra算法。时间复杂度O(n^3)。 考虑下列变形:如(I,j)∈E则dis[I,j]初始为1,else初始为0,这样的Floyd算法最后的最短路径矩阵即成为一个判断I,j是否有通路的矩阵。更简单的,我们可以把dis设成boolean类型,则每次可以用“dis[I,j]:=dis[I,j]or(dis[I,k]and dis[k,j])”来代替算法描述中的蓝色部分,可以更直观地得到I,j的连通情况。

[Mathimatics-Numerical algorithmsfloyd_warshall

Description: 用C语言实现最短路径算法中的Floyd-Warshall算法,这个算法可以用来解决信号处理中的一些问题。floyd_warshall.c是源程序;distance_2.txt文件存放图中各点之间的距离,以99999表示无穷大;floyd.txt文件是输出文件,其中存放各轮得到的输出矩阵,以及最后得到的各点间最短距离,如果有负回路则返回FALSE。-C language shortest path algorithm of Floyd-Warshall algorithm, The algorithm can be used to solve signal processing some of the problems. Floyd_warshall.c yes source; distance_2.txt document storage map of the distance between points, 99,999 said to infinity; floyd.txt document output files, which kept the round of the output matrix, and finally come to the point of the shortest distance, If there is a negative loop it returns FALSE.

Description: 用最短路径算法算出特定两点之间的距离 输入:直接读取net.in文件 第一行为四个整数N,M,S,T,每两个整数之间用一个空格隔开,分别表示网络的节点(编号为1到N),网络线段数,以及起点终点编号 接下来M行,每行三个整数U,V,D,每个整数之间用空格隔开,表示节点U和V之间有一条线路相连,距离是D,(两个节点可能有多条线路) 输出:直接写入到net.out文件,输出只有一行,表示从S点到T点的最短距离(如果不通则输出-1) (N<=100,M<=N*N,D<=1000)(Use the shortest path algorithm to calculate the distance between two specific two points Input: read the net.in file directly The first behavior is four integers N, M, S and T. Every two integers are separated by a space, representing the node of the network (number 1 to N), the number of network segments, and the origin and destination number. Next, M row, each row three integers U, V, D, each integer is separated by spaces, indicating that there is a line between nodes U and V, the distance is D, (there may be multiple lines in two nodes). Output: write directly to net.out file, output only one line, which indicates the shortest distance from S point to T point (if it doesn't connect, output -1) (N<=100, M<=N*N, D<=1000).
