....SCIENCE FOUNDATION founded by The Israel Academy of Sciences and Humanities. 1 Phillips [KKP93] and McGeoch [McG95] For undirected graphs with nonnegative integer edge weights, a running time of O(mn) can be obtained by running a recent single source shortest paths algorithm of Thorup [Tho99] [Tho00] from each vertex of the graph. The running time of all the above mentioned algorithms may be as high as n 3 ) Can the APSP problem be solved in sub cubic time Fredman [Fre76] showed that the APSP problem for weighted directed graphs can be solved non uniformly in O(n 2:5 ) time. More ....

....graph problems. The APSP problem for directed or undirected graphs with real weights can be solved using classical methods, in O(mn n 2 log n) time (Dijkstra [4] Johnson [10] Fredman and Tarjan [7] or in O(n 3 ( log log n) log n) 1=2 ) time (Fredman [6] Takaoka [12] Thorup [14] [15] recently showed that for undirected graphs with integer weights, the problem can actually be solved in O(mn) time. In the last decade, it was shown that fast algorithms for algebraic matrix multiplication can be used to obtain faster algorithms for solving the APSP problem in dense graphs with ....
