Abstract: We describe a new external memory data structure, the buffered repository tree, and use it to provide the first non-trivial external memory algorithm for directed breadth-first search (BFS) and an improved external algorithm for directed depth-first search. We also demonstrate the equivalence of various formulations of external undirected BFS, and we use these to give the first I/O-optimal BFS algorithm for undirected trees. 1 Introduction We use the standard I/O model [1], which counts disk...

...SSSP, BFS, and topological sorting all perform C(V) I Os. More precisely, their I O complexity is O(min (V ) log V sort(E) V ) [5, 6, 13]. A number of improved algorithms have been developed for special classes of graphs. For trees for example, O(sort(N) I O...
