Indexing Graph Search Trees and Applications

19 Jun 2019Sankardeep ChakrabortyKunihiko Sadakane

We consider the problem of compactly representing the Depth First Search (DFS) tree of a given undirected or directed graph having $n$ vertices and $m$ edges while supporting various DFS related queries efficiently in the RAM with logarithmic word size. We study this problem in two well-known models: {\it indexing} and {\it encoding} models... (read more)
