Finding all the shortest paths between two nodes in unweighted directed graphs using BFS algorithm

I am working on a problem that I need to find all the shortest path between two nodes in a given directed unweighted graph. I have used BFS algorithm to do the job, but unfortunately I can only print[详细]

Can this breadth-first search be made faster?

I have a data set which is a large unweighted cyclic graph The cycles occur in loops of about 5-6 paths. It consists of about 开发者_运维技巧8000 nodes and each node has from 1-6 (usually about 4-5) c[详细]

What is breadth-first search useful for?

Usually when I\'ve had to walk a graph, I\'ve always used depth-first sear开发者_开发知识库ch because of the lower space complexity.I\'ve honestly never seen a situation that calls for a breadth-first[详细]

Do any POSIX functions or glibc extensions implement a breadth-first file tree walk?

I am writing a daemon that utilizes inotify to monitor file access and it is critical that I don\'t miss anything on a recursive search. I found this interesting idea and have begun to implement it.[详细]
