CP 2011 wishes to promote the presentation of CP applications. We
especially
look for industrial and academic users of constraint technology to
submit
papers on completed or on-going practical projects. Papers comparing
constraint
technology to other optimization techniques (MIP, local search, SAT,
etc.)
with a sound experimental evaluation are also encouraged.

Papers which clearly define users' benefits, describe the required
effort
to build the application and the time frame in which it was
delivered,
will match the acceptance criteria most closely. The novelty of the
application domain, while potentially a plus, is not the only
deciding
acceptance criterion.

    * Application papers will be reviewed by a program committee with
      significant experience in the use of CP in applications.

    * The writing of the paper should be guided by providing
      answers to four main questions (outlined below).

Application papers will appear in the same proceedings as research
papers: 15 page limit.


Suggested Outline
-----------------

Title; Authors/Company

Section 1 - The problem

    * context, description, definition...

    * size of the application (constraint part/others)?

    * how important is the problem? (impact...) in which terms?
(monetary,
      safety, etc.)

    * what is a solution to this problem? (decision, exemplification,
      enumeration, counting, optimisation, approximation, etc.)

Section 2 - Why CP?

    * what was used before? (hand made, LP...)

    * why change? (didn't it work well? difficult to maintain? ...)

    * why/how did you come to CP?

Section 3 - How CP?

    * model, implementation

    * pure CP or hybrid? (is CP used in conjunction with other problem
solving
      techniques such as LP/MIP, SAT, custom heuristic?) which
decomposition
      method?

Section 4 - Added Value of CP?

    * cost of development? / time spent developing the application?

    * how long has it been in production mode (if development
completed)?

    * what is the feedback from user experience (if applicable)?

    * was it difficult/necessary for the end-user to understand
constraint
      technology?

    * what is the return on investment (if applicable)?

    * do you plan any new CP based development?

    * what are the lessons learned from the use of CP?
