In many cases, the addition of metric operators to qualitative temporal logics (TLs) increases the complexity of satisfiability by at least one exponential: while common qualitat...
Given a dataset P, a k-means query returns k points in space (called centers), such that the average squared distance between each point in P and its nearest center is minimized. S...

Verification of partially synchronous distributed systems is difficult because of inherent concurrency and the potentially large state space of the channels. This paper identifies ...
We consider a class of arithmetic equations over the complete lattice of integers (extended with −∞ and ∞) and provide a polynomial time algorithm for computing least solutio...
Shorter counterexamples are typically easier to understand. The length of a counterexample, as reported by a model checker, depends on both the algorithm used for state space explo...
