We establish that the decidability of the first order theory of a class of finite structures ¢ is a simple and useful condition for guaranteeing that the expressive power of FO...
We study the robustness of complete sets for various complexity classes. A complete set A is robust if for any f(n)-dense set S ∈ P, A−S is still complete, where f(n) ranges f...
A sharing community prospers when participation and contribution are both high. We suggest both, while being related decisions every peer makes, should be given separate rational ...
