The distant graph $G = G(\mathbb{P}(Z),\triangle)$ of the projective line over the ring of integers is considered. The shortest path problem in this graph is solved by use of Klein's geometric interpretation of Euclidean continued fractions. In case the minimal path is non-unique, all...
The shortest multiple path problem is stated. Then, we suggest an algorithm for finding the shortest path in a multiple graph. It uses Dijkstra鈥檚 algorithm for finding the shortest paths in subgraphs, which correspond to different reachability sets.A. V. Smirnov...

North-Holland THE SHORTEST-PATH PROBLEM FOR GRAPHS WITH RANDOM ARC-LENGTHS A.M. FRIEZE We consider the problem of finding the shortest distance between all pairs of vertices in a complete digraph on n vertices, whose arc-lengths are non-negative random variables. We describe an algorithm which...
The shortest path problem in the stochastic traffic network is studied. 主要研究随机路网中的最短路径问题,首先给出随机路网的定义,建立了随机路网的模型,假定路段的费用是满足正态分布的随机变量,并给出从历史数据中得到此变量的均值和方差的统计学方法;然后得出路径出行费用的均值及方差的递推公式,将费用的...
题目链接:https://cn.vjudge.net/contest/283066#problem/L 题目大意:T组测试样例,n个点,m条边,每一条边的信息是起点,终点,边权。问你是不是存在负环,如果存在的话输出-inf,否则的话,输出最小路径(两个点之间)。 具体思路:一般的spfa只能判断一个点到其他点的最短距离,但是这个题目让我们求的是任意两个...
This paper addresses the elementary shortest path problem with forbidden paths. The main aim is to find the shortest paths from a single origin node to every other node of a directed graph, such that the solution does not contain any path belonging to a given set (i.e., the forbidden set...
