Technology (The Netherlands), there is a vacancy for a 4 year
PhD-position within the NWO project "Local Symmetries for Global
Success". This PhD position is supervised by Christopher Hojny.
The vacancy can be found at
https://jobs.tue.nl/en/vacancy/phd-position-in-generating-cutting-planes-by-exploiting-symmetry-979779.html
The vacancy remains open until a suitable candidate has been found and
closes definitively on March 5, 2023.
Starting date: preferably first half of 2023
PROJECT DESCRIPTION
Cutting planes and symmetry handling techniques are two of the most
powerful components of mixed-integer programming (MIP) solvers and there
exists a vast amount of literature on both topics. However, despite the
success of both components, there seems to be almost no research on
combining these two fields. This is an unused potential: if a MIP admits
symmetries, then they also carry over to cutting planes.
The goal of this project is to transfer the positive effect of symmetry
handling for an entire MIP to the generation of cutting planes. Among
others, we will explore how symmetries can be used to generate cutting
planes faster and to strengthen weak cutting planes in general MIP
software. This project also gives the opportunity to evaluate the
practical performance of the developed techniques in the
state-of-the-art MIP software SCIP.
The successful candidate for this PhD position will work under the
supervision of Christopher Hojny in the group Combinatorial Optimization
(https://www.tue.nl/en/research/research-groups/mathematics/statistics-probability-and-operations-research/combinatorial-optimization-1/)
of the department of Mathematics and Computer Science of TU/e. Your
responsibilities include to perform scientific research on the topic of
the above-mentioned project and to publish your results at international
conferences and in international journals. For a small percentage of
your time, you will be asked to assist with educational tasks (course
support and supervision of students).
JOB REQUIREMENTS
You have a master degree in (Applied) Mathematics or a related field.
- You have a strong background in Integer Programming, Discrete
Optimization, and Combinatorial Optimization.
- You are enthusiastic about programming, preferably in C.
- You have good communication skills.
- You are creative, ambitious, as well as self-motivated, proactive, and
goal-oriented.
- You have a good command of the English language (knowledge of Dutch is
not required).
CONDITIONS OF EMPLOYMENT
A meaningful job in a dynamic and ambitious university, in an
interdisciplinary setting and within an international network. You will
work on a beautiful, green campus within walking distance of the central
train station. In addition, we offer you:
- Full-time employment for four years, with an intermediate evaluation
(go/no-go) after nine months. You will spend 10% of your employment on
teaching tasks.
- Salary and benefits (such as a pension scheme, paid pregnancy and
maternity leave, partially paid parental leave) in accordance with the
Collective Labour Agreement for Dutch Universities.
- A year-end bonus of 8.3% and annual vacation pay of 8%.
- High-quality training programs and other support to grow into a
self-aware, autonomous scientific researcher. At TU/e we challenge you
to take charge of your own learning process.
- An excellent technical infrastructure, on-campus children's day care
and sports facilities.
- An allowance for commuting, working from home and internet costs.
- A Staff Immigration Team and a tax compensation scheme (the 30%
facility) for international candidates.
