Workshop on Progress Towards the Holy Grail

This was a joint workshop of CP2017, ICLP2017 and SAT2017 . It was held on August 28, 2017 in Melbourne, Australia.

Twenty years previously the paper “In Pursuit of the Holy Grail” proposed that Constraint Programming was well-positioned to pursue the Holy Grail of computer science: the user simply states the problem and the computer solves it. This workshop looked at progress towards that goal, specifically regarding work on automating:

  • Problem Acquisition: learning from examples, model reformulation, etc.
  • Solver Construction: tuning parameters, selecting from portfolios, etc.
  • User Explanation: reasons for failure, implications of choices, etc.

The increasing interest in Human-Aware AI and intelligent software assistants made this a particularly timely topic.

Panel

Once and Future

At CP 2006, there was a workshop on The Next 10 Years of Constraint Programming. There was a Constraint Programming Letters special issue and a book chapter (chapter 3 of Trends in Constraint Programming) that grew out of the 2006 workshop. This Panel was designed to look back at that workshop to see how the proposals and predictions panned out, and to discuss where we go from here. The subject of the Panel is broader than the subject of the Workshop, of course, but overlaps. In particular: where do we go from here in Pursuit of the Holy Grail?

Panelists: John Hooker, Mark Wallace, Roland Yap
