An Approximation Algorithm for Weighted Weak Vertex Cover Problem in Undirected Graphs
The problem of efficiently monitoring the network flow is regarded as the one to find out the minimum weighted weak vertex cover set for a given graph G = (V, E) with weight func...

On-Line Construction of Compact Directed Acyclic Word Graphs
Directed Acyclic Word Graph (DAWG) is a space efficient data structure that supports indices of a string. Compact Directed Acyclic Word Graph (CDAWG) is a more space efficient vari...

Radial Coordinate Assignment for Level Graphs
We present a simple linear time algorithm for drawing level graphs with a given ordering of the vertices within each level. The algorithm draws in a radial fashion without changing...

Bicriteria Network Design via Iterative Rounding
We study the edge-connectivity survivable network design problem with an additional linear budget constraint. We give a strongly polynomial time (3, 3)-approximation algorithm for ...

Explaining and Controlling Ambiguity in Dynamic Programming
Abstract. Ambiguity in dynamic programming arises from two independent sources, the non-uniqueness of optimal solutions and the particular recursion scheme by which the search spac...
