LSCS is a satellite workshop of the international conference on principles and practice of Constraint Programming (CP), since 2004. It is devoted to local search techniques in constraint satisfaction, and focuses on all aspects of local search techniques, including: design and implementation of new algorithms, hybrid stochastic-systematic search, reactive search optimization, adaptive search, modeling for local-search, global constraints, flexibility and robustness, learning methods, and specific applications.

In 2009, there was five long presentations of 30 minutes, and three short presentations of 15 minutes. The workshop programme also included an invited talk by Thomas Stützle on Engineering Stochastic Local Search.

We thank all reviewers who provided valuable remarks on the submitted papers, and CP organisers for their material support.
