LSCS 2005 Workshop

 


Call for Papers and Participation

Second International Workshop on Local Search Techniques in Constraint Satisfaction
in conjunction with CP 2005


Overview and Scope

LSCS is an annual workshop devoted to local search techniques in constraint satisfaction. This workshop focuses on all aspects of local search techniques, including: design and implementation of new algorithms, hybrid stochastic-systematic search, winning heuristics, modeling for local-search, global constraints, learning methods, and specific applications. The workshop will provide an informal environment for discussions about recent results in these and related areas. It is open to all members of the CP community.

Papers are solicited from the above areas or from any other area related to local search in constraint satisfaction. In addition to contributed papers, we will have one invited lecture and will also provide opportunities for short presentations of post-deadline important results.

Submissions

Authors should prepare their full papers in the CP format, by following the Springer instructions. The maximum is 15 pages. Extended abstracts of post-deadline important results should be no longer than two pages, including figures and references.

Papers and abstracts submitted to the workshop will be reviewed by at least two members of the program committee. Decisions about acceptance or rejection will be made considering both the merit of the paper and the available time for presentations. At least one author of each accepted submission must attend the workshop. All workshop participants must pay the workshop's fees. This payment provides admission to all CP/ICLP workshops. Payment of the CP/ICLP main conference fees is NOT required for participation in the workshop.

Submissions should be made electronically, by sending papers or post-deadline abstracts in PDF format to: Yehuda Naveh (naveh@il.ibm.com).

Each submission should identify one contact author, and provide the email address and phone number of this author. Contact authors should expect an acknowledgment of receipt within two business days of submission.
