We present a polynomial-time algorithm which at the extra cost of a factor O(k) (k the number of variables) generalizes inter-procedural copy constant propagation. Our algorithm in...
The problem of model checking threads interacting purely via the standard synchronization primitives is key for many concurrent program analyses, particularly dataflow analysis. U...
A discrete pushdown timed automaton is a pushdown machine with integer-valued clocks. It has been shown recently that the binary reachability of a discrete pushdown timed automaton...
Abstract. We present a general theory that exploits simulation relations on transition systems to obtain antichain algorithms for solving the reachability and repeated reachability...
Abstract. Regular expressions with numerical constraints are an extension of regular expressions, allowing to bound numerically the number of times that a subexpression should be m...
