We show that the satisfiability problem for bounded-error probabilistic ordered branching programs is NP-complete. If the error is very small, however (more precisely, if the erro...
We collected and analyzed a number of linear programming problems that have been shown to cycle (not converge) when solved by Dantzig's original simplex algorithm. For these ...
In the current state of the rapid growth of information resources and the huge number of requests submitted by users to existing information retrieval systems; recently, Question ...
—This paper seeks to answer fundamental questions about trade-offs between static and dynamic security analysis. It has been previously shown that flow-sensitive static informat...
Several authors have proposed using code modification as a technique for enforcing security policies such as resource limits, access controls, and network information flows. Howeve...
