Towards a Theory of Time-Bounded Verificationand ., in that the restriction to bounded time domains reclaims as decidable several of the key decision problems of unbounded real-time verification. Finally, we discuss several directions of ongoing and future work.

Physical Algorithmsand dynamics. The networked systems we envision include traditional computer networks, but also more generally networked systems, such as social networks, highly dynamic and mobile networks, or even networks of entities such as cars or ants. In other words, the world is becoming algorithmic, and we need the means to analyze this world!

Optimal Zielonka-Type Construction of Deterministic Asynchronous Automataze of the obtained asynchronous automaton is polynomial in the size of a given DFA and simply exponential in the number of processes. We show that our construction is optimal within the class of automata produced by Zielonka-type constructions. In particular, we provide the first non trivial lower bound on the size of asynchronous automata.

Pumping and Counting on the Regular Post Embedding Probleme variant problems where the set of solutions is compared to regular constraint sets and where one counts the number of solutions. Our positive results rely on two non-trivial pumping lemmas for Post-embedding languages and their complements.

An ,(log,)-Competitive Online Centralized Randomized Packet-Routing Algorithm for Lineses and communication link capacities. In particular, it holds also for unit buffers..This algorithm improves the best previous .(log..)-competitive ratio of [6] and considers links with unit capacities.

On Erasing Productions in Random Context Grammarsontext grammars have the same generative capacity as matrix grammars without appearance checking..The main result is a positive answer to the first question. For the other two, conjectures are presented. It is then deduced from the main result that at least one of the two holds.

Getting StartED with Mac OS X Leopardthe .-th level is strictly smaller than the tower of . of height .. As a corollary the Cantor-Bendixson rank of the tree solutions of safe recursion schemes of order . is smaller than the tower of . of height ...As a spin-off result, we show that the .-words belonging to the second level of the pushdown hierarchy are exactly the morphic words.

Getting StartED with Mac OS X Leopardact state space that is guided by examples, meaning that it preserves spuriousness of examples (i.e., abstract paths). In particular, we show how EGAS can be integrated with the well-known CEGAR (CounterExample-Guided Abstraction Refinement) methodology.
