Research over the last two decades has shown that integration of ideas from mathematical programming and constraint programming (CP) can simplify modeling and reduce solution time significantly. A substantial share of the speedup is due to better communication of problem structure to the solver through metaconstraints, a generalization of global constraints in CP. However, metaconstraints pose the problem of identifying relationships between auxiliary variables that are introduced when the solver unpacks the constraints. We propose a semantic typing system as a general solution to this problem. Variables are defined by their association with typed predicates and keywords, where the keywords are analogous to database queries. We present examples to illustrate this modeling paradigm over a wide variety of applications. This is joint work with Andre Cire and Tallys Yunes.

Bio:
John Hooker is the T. Jerome Holleran Professor of Business Ethics and Social Responsibility and Professor of Operations Research at Carnegie Mellon University.  He joined the Tepper School of Business at CMU in 1984 and has since held several visiting posts, most recently at the London School of Economics and the State University of Campinas, Brazil.  He holds doctoral degrees in philosophy and operations research.

Professor Hooker has published over 130 articles, 6 books, and 5 edited volumes.  In the area of operations research, he has produced pioneering work on the integration of optimization technologies and wrote the first book on the subject. He is also the author of Optimization Methods for Logical Inference and two editions of Integrated Methods for Optimization.  He has served on several editorial boards, including two decades as an area editor for INFORMS Journal on Computing.  He is an INFORMS Fellow and recipient of the INFORMS Computing Society Prize.

He also has interests in business ethics and cross-cultural management, as reflected in his books Business Ethics as Rational Choice and Working across Cultures.  He is founding editor-in-chief of the Journal of Business Ethics Education and co-organized four conferences on international corporate responsibility.  He has lived and worked in Australia, Brazil, China, Denmark, India, Qatar, Turkey, the United Kingdom, the United States, and Zimbabwe, and has extensive experience in Germany and Mexico.

Professor Hooker headed the Tepper School’s undergraduate business administration program from 1996 to 2001 and received a Distinguished Academic Service Award for his contributions. In 2009, he was recognized with an Award for Sustained Teaching Excellence.

I did this last year.  It was fantastic, one of the best weeks of my life (so far).  It's like summer camp for Optimization lovers.  There is no cell service at the site (which also happens to be next to a world class beach), so you are sure to enjoy a lot of old-fashion, quality-time with the attendees.

Surely worth the trip to Australia.
What: Optimisation Summer School When: 12--17 January 2014 Where: Kioloa Beach, New South  Wales Registration and further details: http://www.cse.unsw.edu.au/~tw/school/programme.html Applications ...

that's pretty terrible. seems like the sequester nonsense has followed you across the Pacific!

also, I can see the Coalition cutting funding to those basic science peeps over at CSIRO, but NICTA? c'mon -- it's basically research for business and the economy. :-)

only good thing about this election is The Chaser's take on it ("The Hamster Decides"): https://www.youtube.com/user/ChaserEpisodes/feed?filter=2

Always wanted to take this at Brown.  So glad I have the chance again!
 
My free online course, Coding the Matrix:  Linear Algebra through Computer Science Applications, starts Monday, July 1.  It's aimed at people who know how to program and want to leverage that knowledge to learning about vectors and matrices and their applications.  A short follow-on course covering more advanced topics is in the works.

How do we go about proving that a puzzle such as Candy Crush is hard to solve? What makes noughts and crosses easy, but Candy Crush hard? Find out in this article by +Toby Walsh

It was a major effort in preparing these designs, but well worth the effort.
