Given string T = T[1, . . . , n], the suffix sorting problem is to lexicographically sort the suffixes T[i, . . . , n] for all i. This problem is central to the construction of suf...
ABSTRACT. We study the problem of space-efficient polynomial-time algorithms for directed stconnectivity (STCON). Given a directed graph G, and a pair of vertices s, t, the STCON ...
Abstract. Notations like SGML and XML represent document structures using tree structures; while this is in general a step forward from earlier systems, it creates certain difficul...
