Yen's算法是Yen 在1971 年提出的以其名字命名 的Yen 算法。Yen's算法采用了递推法中的偏离路径算法思想,适用于非负权边的有向无环图结构。 算法思想 算法可分为两部分,算出第1条最短路径P(1),然后在此基础上依次依次算出其他的K-1条最短路径。在求P(i+1) 时,将P(i)上除了终止节点外的所有节点都...
This function is based on Yen's k-Shortest Path algorithm: J. Y. Yen, "Finding the K shortest loopless paths in a network", Management Science 17:712–716, 1971. It returns: 1) [shortestPaths]: the list of K shortest paths (in cell array 1xK) ...
Yen's K-Shortest Path Algorithm Yen's algorithm computes single-source K-shortest loopless paths for a graph with non-negative edge cost. The algorithm was published by Jin Y. Yen in 1971 and implores any shortest path algorithm to find the best path, then proceeds to find K − 1 devi...

K最短路径算法分类 二、思路 下面列出用Yen's算法求KSP的代码。该算法是Yen在1971年提出的以其名字命名的Yen算法。算法采用了递推法中的偏离路径算法思想,适用于非负权边的有向无环图。 1.流程图 Q:将什么样的点做为偏离点 在pk的基础上求pk+1时,将pk的路径上除终点d之外的节点分别作为偏离点 ...
我需要一个algorithm(k, s) 给定无向图中所有节点相互链接的n数,返回k路径遍历所有节点,其中k路径覆盖的距离之和最短。例如,给定n = 10,algorithm(2,5)可能给出一个由两个数组组成的数组,使得两个路径所覆盖的距离之和最短,并且所有节点都被遍历。[[5 浏览2提问于2014-10-20得票数 1 ...
