Updated Website Announcement

Dear PATAT community,

The PATAT community was launched in the wake of the first international conference on the Practice and Theory of Automated Timetabling in 1995 (PATAT'95). Ever since, the interest group has flourished and memberships have steadily increased.

We are pleased to announce the release of a new website (patat.cs.kuleuven.be) and a new mailing list (watt@ls.kuleuven.be). From now on, these channels will be used to spread timetabling news in the community and beyond!

Dear members of the EURO working group on Automated Timetabling (WATT),

*** Please distribute this message among timetabling researchers ***

EURO - The association of European Operational Research Societies -
encourages its EURO working groups to support members from weak currency
countries and early stage OR researchers.

In compliance with this EURO charter, WATT - The EURO working group on Automated Timetabling - has decided to sponsor two PhD students by paying their registration to the 11th
International Conference on the Practice and Theory of Automated Timetabling (PATAT 2016).

Candidates should:

- be registered as a student in a weak currency country or be an early stage OR researcher (actual Ph.D. students and post-doctoral researchers for a period not exceeding two years after
their Ph.D. defence);

- submit an abstract by 31 May 2016 (follow the instructions at http://www.patatconference.org/patat2016/instructions/);


- provide the abstract/paper number accepted in the regular call for papers/abstracts;

- submit a letter of support by their university supervisor.
The quality of the abstracts will be assessed by reviewing as usual.  The
winning Ph.D. students will be informed by 15 June 2016."

best regards,

Sanja Petrovic and Greet Vanden Berghe (WATT coordinators)
