Over-Approximating Boolean Programs with Unbounded Thread Creation
Abstract-- This paper describes a symbolic algorithm for overapproximating reachability in Boolean programs with unbounded thread creation. The fix-point is detected by projecting ...

Improved Approximations for TSP with Simple Precedence Constraints
In this paper, we consider variants of the traveling salesman problem with precedence constraints. We characterize hard input instances for Christofides' algorithm and Hoogeve...
