We present an O(m + n)-time algorithm that tests if a given directed graph is 2-vertex connected, where m is the number of arcs and n is the number of vertices. Based on this resul...
We consider dictionaries over the universe U = {0, 1}w on a unit-cost RAM with word size w and a standard instruction set. We present a linear space deterministic dictionary with m...
Abstract. We present algorithms for maintaining shortest path information in dynamic outerplanar digraphs with sublogarithmic query time. By choosing appropriate parameters we achi...

Fully automatic methods that extract lists of objects from the Web have been studied extensively. Record extraction, the first step of this object extraction process, identifies...
Currently, only few XML data management systems support concurrent access to an XML document, and if they do, they typically apply variations of hierarchical locking to handle XML...
