An Improved Approximation Bound for Spanning Star Forest and Color Saving
We present a simple algorithm for the maximum spanning star forest problem. We take advantage of the fact that the problem is a special case of complementary set cover and we adapt...

Query Evaluation via Tree-Decompositions
A number of efficient methods for evaluating first-order and monadic-second order queries on finite relational structures are based on tree-decompositions of structures or quer...

Fast Formal Analysis of Requirements via "Topoi Diagrams"
Early testing of requirements can decrease the cost of removing errors in software projects. However, unless done carefully, that testing process can significantly add to the cos...

Weaknesses in the Key Scheduling Algorithm of RC4
Abstract. Inthis paper we present several weaknesses in the keyscheduling algorithm of RC4, and describe their cryptanalytic signi cance. We identify a large number of weak keys, i...

Partial Simulation-Driven ATPG for Detection and Diagnosis of Faults in Analog Circuits
In this paper, we propose a novel fault-oriented test generation methodology for detection and isolation of faults in analog circuits. Given the description of the circuit-underte...
