Overview

User-interaction issues arise both for users of constraint programming languages and for users of constraint-based applications. The former need assistance in building models and tailoring solvers. The latter need assistance in specifying problems and understanding results. Successful user interaction is the key to fully exploiting advances in constraint solving abilities.

This workshop will be of interest to researchers who wish seek a deeper understanding of the technical issues associated with supporting user interaction for constraint-based applications, languages or environments. The workshop will also be of interest to industrialists interested in the state-of-the-art in the area.

Scope

The scope of the workshop includes, but is not limited to, the following topics:

  • acquiring constraints and preferences;
  • explaining success and failure;
  • interactive constraint satisfaction;
  • modifying over-constrained and under-constrained problems;
  • constraint programming development environments;
  • debugging tools;
  • interacting with constraint-based agents;
  • distributed constraint satisfaction;
  • negotiation;
  • privacy;
  • coping with unreliability, uncertainty and change;
  • application environments, e.g. configuration, design, network management, scheduling.

Delivery & Submissions

This workshop will be scheduled for a half day. We expect to structure the Workshop to allow ample time for discussion and demonstration. We would like to avoid a "mini-conference".

All workshop attendees must pay the CP workshop registration fee.

Prospective attendees can:

  • Submit a paper, which can be up to 15 pages in length.
  • Submit a one page statement of interest in plain text e-mail, indicating what perspective and background they will bring to the Workshop.
  • Submit a position paper discussing ``what users need''.

"Real users" are especially welcome to seek attendance to provide their perspectives.

A special issue of the Constraints Journal (Kluwer) on user-interaction is planned, should the submissions warrant. This special issue would contain selected papers from the workshop, which had undergone further revision and review.

We encourage authors to submit papers electronically in postscript format. Papers should be formatted using the Lecture Notes in Computer Science (LNCS) style.

Please send your submissions by email to b.osullivan@cs.ucc.ie using the subject line CP Workshop Submission.
