Subject: Nonlinear Optimization in Constraint Prog, Canada, Oct 2012

Call for Abstracts
Workshop on Nonlinear Optimization in Constraint Programming

To be held within the 18th International Conference on Principles and
Practice of Constraint Programming (CP 2012), Québec City, Canada

https://sites.google.com/site/minlpworkshop2012

This workshop has the purpose of bringing together scholars that work
on Mixed Integer Nonlinear Programming (MINLP) problems, which combine
nonlinear constraints with integrality on one or more variables. The
organizing committee invites submissions of a short abstract (not more
than 4000 characters) describing original work on a problem or
application of MINLP, CP, or both, with a special emphasis on the
nonlinear characteristics of the problem. Topics of interest include
(but are not limited to):
- Domain reduction techniques in Global optimization;
- Quadratically constrained quadratic programming;
- Reformulations in MINLP solvers;
- Using CP methods in MINLP solvers;
- Software for MINLP and CP;
- Decomposition techniques for large scale MINLP and CP problems;
- Challenging real-world applications of MINLP and CP.

The submissions will be evaluated by the program committee and a
selection of abstracts will be admitted for presentation at the
workshop. Registration at the CP2012 conference is necessary to attend
and present at the workshop. Abstracts can be emailed to Pietro
Belotti (pbelott@clemson.edu).

August 31, 2012: Abstract submission due

Subject: Lectureship Position, Univ of Strathclyde

Applications are invited from suitably qualified candidates for a
permanent academic post in the Department of Mathematics and
Statistics at the University of Strathclyde, Glasgow UK.

You will have responsibilities for teaching, research and
administration, and have strong research interests in any area of
Applied Mathematics and Statistics. The Department has a wide range
of research interests including numerical analysis, stochastic
computation and high performance computing. One responsibility of the
post will be to provide academic oversight of our new masters degree
in Quantitative Finance and so it would be desirable (but not
essential) that the candidate has a background in relevant areas, such
as mathematical or computational finance, and/or a willingness to
develop their research in this direction.
