Verification of qualitative Z constraints
We introduce an LTL-like logic with atomic formulae built over a constraint language interpreting variables in Z. The constraint language includes periodicity constraints, comparis...

Universal Causality Graphs: A Precise Happens-Before Model for Detecting Bugs in Concurrent Programs
Triggering errors in concurrent programs is a notoriously difficult task. A key reason for this is the behavioral complexity resulting from the large number of interleavings of op...

Automatic Generation of Symmetry-Breaking Constraints
Solution symmetries in integer linear programs often yield long Branch-and-Bound based solution processes. We propose a method for finding elements of the permutation group of sol...
