Cache-Oblivious Data Structures and Algorithms for Undirected Breadth-First Search and Shortest Paths

By Gerth Stølting Brodal, Rolf Fagerberg, Ulrich Meyer and Norbert Zeh


We present improved cache-oblivious data structures and algorithms for breadth-first search and the single-source shortest path problem on undirected graphs with non-negative edge weights. Our results close the performance gap between the currently best cache-aware algorithms for these problems and their cache-oblivious counterparts. Our shortest-path algorithm relies on a new data structure, called bucket heap, which is the first cache-oblivious priority queue to efficiently support a weak DecreaseKey operation
