My Constraint Programming Blog

Friday, Day 4 (last day

After yesterday's quite hectic agenda, today was was - for me at least - a much more relaxed day. Though the organizers and the organge guys was busy to the last minute.

First, I would like to thank all the organizers and the "volunteers" [the quotes was official] for a really well organized and interesting conference. It was my first CP-conference so I didn't really know what to expect, but it was just fun being there, both for the talks but also to meet and discuss CP with the leading experts in the field (or just listening to their discussions).

So, the day was fun and started with the invited talk by Torsten Schaub on ASP (Answer Set Programming), which is a paradigm different from CP in details but quite close in goals and some principles. The system mentioned was Potassco. You can see more about it at my Answer Set Programming page.

After Torsten's talk was the Modeling track with very interesting talks, and I especially liked the CP systems talks : Ozgur Akgun talked about Automated Symmetry Breaking and Model Selection in Conjure. More about Conjure is here.

After that Daniel Fontaine talked about "Model Combinatorics for Hybrid Optimization" in Objective-CP (sorry there is no link to Objective-CP yet) and then Kevin Leo about "Globalizing Constraint Models", a project which tries to automatically make more efficient MiniZinc models.

The tutorial by Phil Kilby about CP for Vehicle Routing Problems was very inspiring. He explained a general CP model which can solve many of the different VRP problems. Really interesting and important stuff.

Last session for the day, and the conference, was "Global Constraints and Conflicts" with four talks which - I have to admit - sometimes was a bit over my head. Though I think that the results they showed was quite impressive.

And the conference is now all. Again, thanks for organizing this! And thanks to all wonderful, inspiring, and bright people in the CP world.

This is last daily report blog post as the CP-2013's official blogger. Hope you have enjoyed it as much as I when writing it; blogging is a great way to digest things. Feel free to contact me in CP related matters: hakank@gmail.com.

Oh, I almost forgot today's first greetings with e-contacts (with a slightly extended meaning of e-contacts): Torsten Schaub, Toby Walsh, Christopher Mears, Roland Yap, Thibaut Feydy.
