Opis

The Third International Workshop on Reachability Problems, RP 2009 was held in Ecole Polytechnique, September 23-25, 2009, in Palaiseau, near to Paris, France. Reachability Problems 2009 was hosted as an edition of the annual LIX Fall Colloquium. The LIX Fall Colloquium is the annual colloquium organized by the computer science laboratory of Ecole Polytechnique. The topics of this c- loquiumchange everyyear. Previouseditions includeEmerging Trends in Visual Computing (ETVC 2008) in 2008, Complex Industrial Systems: Modeling, Ve- ?cationandOptimization in2007, and Emerging TrendsinConcurrencyTheory in 2006.

Analysis of the computational traces and predictability questions for such models can be formalized as a set of di?erent reachability problems. In general reachability can be formulated as follows: Given a computational system with a set of allowed transformations (functions), decide whether a certain state of a system is rea- able from a given initial state by a set of allowed transformations. The same questions can be asked not only about reachability of exact states of the system but also about a set of states expressed in term of some property as a pa- meterized reachability problem. Another set of predictability questions can be seen in terms of reachability of eligible traces of computations; unavoidability of some dynamics and a possibility to avoid undesirable dynamics using a limited control.

This book constitutes the research papers presented at the 3rd International Workshop, RP 2009 held in Palaiseau, France, September 23-25, 2009.

The 20 full papers of this workshop reflect reachability problems that appear in algebraic structures, computational models, hybrid systems and verification. Reachability is a fundamental problem in the context of many models and abstractions which are describing various computational processes.

Topics of interest include reachability problems in infinite state systems, rewriting systems, dynamical and hybrid systems, reachability problems in logic and verification, reachability analysis in different computational models, counter, timed, cellular, communicating automata, Petri-Nets, computational aspects of algebraic structures and predictability in iterative maps and new computational paradigms.
