Efficient algorithms for finding critical subgraphs
This paper presents algorithms to find vertex-critical and edgecritical subgraphs in a given graph G, and demonstrates how these critical subgraphs can be used to determine the ch...

A fast and efficient algorithm for low-rank approximation of a matrix
The low-rank matrix approximation problem involves finding of a rank k version of a m ? n matrix AAA, labeled AAAk, such that AAAk is as "close" as possible to the best ...

Discontinuity-induced bifurcations in TCP/RED communication algorithms
— In this paper, we describe a simple second-order discrete-time model for the Transmission Control Protocol (TCP) with Random Early Detection (RED) algorithm. The TCP/RED mechan...

Approximation Algorithms for the Bi-criteria Weighted max-cut Problem
Abstract. We consider a generalization of the classical max-cut problem where two objective functions are simultaneously considered. We derive some theorems on the existence and th...
