welcome

The IJCAI-09 Workshop on Nonmonotonic Reasoning, Action and Change is the eighth workshop in the popular and successful "NRAC" series. The workshop will be held at the 2009 International Joint Conference on Artificial Intelligence on Saturday, July 11, 2009.

program and invited speaker

We are pleased to announce the NRAC 2009 program. The keynote speaker is Professor Hector Geffner from ICREA and UPF in Spain:

Representation and Inference in Modern Planning:
From Classical Plans to Finite-State Controllers

Planning is concerned with the development of solvers for a range of models where actions must be executed to achieve goals. In these models, actions may be deterministic or not, states may be observable or not, and so on. The challenge in all cases is computational: how to scale up to large problems even if the models are all intractable. In the last last 10-15 years significant progress has been made in the area resulting from novel inference techniques and transformations.

In this talk, I'll review these techniques, as we consider the computation of classical and conformant plans for unobservable problems, and finite-state controllers for partially observable ones.

Joint work with Blai Bonet, Hector Palacios, colleagues and students.
