Recent work by Elmasry et al. (STACS 2015) and Asano et al. (ISAAC 2014), reconsidered classical fundamental graph algorithms focusing on improving the space complexity. Elmasry et al. gave, among others, implementations of breadth first search (BFS) and depth first search (DFS) in a graph on n vertices and m edges, taking O(m + n) time using O(n) and O(n lg lgn) bits of space respectively improving the naive O(n lgn) bits implementation. We continue this line of work focusing on space. Our… CONTINUE READING
