The Doctoral Programme of the Eleventh International Conference on Principles and Practice of Constraint Programming, CP 2005, Sitges(Barcelona), Spain, October 1-5, 2005.

Doctoral Programme is a forum held during the CP conference which provides an opportunity for a group of Ph.D. students to achieve visibility and discuss their research interests and career objectives with each other and established researchers in Constraint Programming. After successful Doctoral Programmes in previous years, it is being run again this year for the fifth time. The aims of the Doctoral Programme are the following: * to provide a forum for Ph.D. students to present their current research, and receive feedback from other students and senior researchers; * to promote contacts among Ph.D. students and senior researchers working in the same area; * to exchange research experience; * to support Ph.D. students with information and advice on academic, research and industrial careers; * and to financially support its participants This year, 50 students are participating to the Doctoral Programme. The participants receive complimentary conference registration and accommodation in double room. Moreover, a short version of the students' abstracts (1 page) will be published in the conference proceedings which will be published by Springer Verlag. The programme consist of presentations and posters of the students who do not have any paper/poster accepted at the main technical programme, and tutorials given by senior researchers in the field. In addition, each student is matched to a mentor who is a senior researcher with similar research interests and who can advise the student on his/her research progress. Finally, a doctoral dinner is organised to bring together the students in an informal gathering.
