K条最短路径算法:Yen's Algorithm 算法背景 K 最短路径问题是最短路径问题的扩展和变形。1959 年,霍夫曼(Hoffman) 和帕夫雷(Pavley)在论文中第一次提出k 最短路径问题。 k 最短路径问题通常包括两类:有限制的k 最短路问题和无限制的K 最短路问题。 前者要求最短路径集合不含有回路,而后者对所求得的最短路径...
1) [shortestPaths]: the list of K shortest paths (in cell array 1xK) 2) [totalCosts] : costs of the K shortest paths (in array 1xK) Yen's algorithm prevents loops. This function calls a slightly modified/simplified function dijkstra() (submitted by Xiaodong Wang, 2004) ...
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...

yenpathy is an R package to quickly find k shortest paths through a weighted directed graph using Yen’s Algorithm. This algorithm has numerous applications in network analysis, such as transportation planning. There are already comprehensive network analysis packages in R, notably igraph and its ti...
