The goal of this seminar is to bring together researchers working in two complementary fields: This combines a strong thread of current research in automata theory with an area of possible but so far unexplored applications.

The paradigm of two-player games (with or without termination) captures a basic situation in reactive systems: A system (control component) "plays against nature": it performs actions in an arbitrary or even hostile environment and has to guarantee certain properties of the evolving sequence of moves, carried out in alternation between system and environment.

Results of the 1960's (of Büchi, McNaughton, Rabin, and others) created a methodology for automatically synthesizing control programs from specifications of the desired global behaviour. In recent years, this algorithmic theory of infinite games produced efficient procedures for strategy construction, opened applications in model-checking, and obtained progress in generalizing the framework to infinite-state, stochastic, and timed systems.

Classical AI planning refers to single-agent deterministic domains. Currently, a more general view is being developed, covering universal planning, extension by nondeterminism and probability distributions (decision-theoretic planning), planning under sources of uncertainty, and the integration of planning and learning. In these topics, AI planning shows close links to the synthesis of reactive control programs - in fact, one can argue that the two fields have the same subject matter and are distinct only by historic conditions.

In this seminar, an attempt will be made to merge the two fields: to apply algorithmic synthesis in AI planning, and at the same time to single out interesting scenarios for further developing the automata theoretic framework. We expect that the workshop will help to increase the interaction and collaboration of the two fields, and the transfer of methodologies from one field to another.
