Abstract: In this paper a new algorithm about searching for the shortest path in a weight graph is introduced. Taking the traffic network into consideration, the algorithm is based on the edges searching. This algorithm is better than the Floyd algorithm in average time complexity.

摘要: 对全源最短路径搜索算法进行了深入的研究分析,并结合国内城市道路交通的实际情况,提出了基于边序列最短路径搜索算法的一种改进算法——EBSP*算法。该算法在平均时间复杂度上比传统的Floyd最短路径搜索算法有较大的提高。
