We are looking for two talented and motivated students with a strong interest in the theory and practice of Integer Programming (IP). The research will be supported by the ERC grant "Towards a Quantitative Theory of Integer Programming". The goals of this research are (1) to develop a quantitative theory that can explain the effectiveness of the prevalent techniques used for solving IPs (e.g. branch & bound, cutting planes, diving heuristics, etc.), (2) to develop new and effective techniques for solving IPs and (3) to build new connections between the study of IP, theoretical computer science and optimization. The research projects are designed to be interdisciplinary and are expected to require combining techniques from various areas of optimization (first order methods, interior point methods, simplex algorithms), theoretical computer science (discrepancy theory, fixed parameter tractability, smoothed analysis) and geometry (convex geometry, geometry of Euclidean lattices). Some sample research questions include:
Supervised by: Daniel Dadush (website)
The PhD candidate is required to have a strong background in at least one of the following areas: optimization, theoretical computer science or discrete mathematics. Research experience within the domain of IP (theory or practice) is a plus. The most important qualification however is an open mind and the ability to pick up new material quickly. Candidates are expected to have an excellent command of English, and good academic writing and presentation skills. The PhD candidate will be expected to conduct research on topics relevant to the above agenda, to publish this research at either top conferences or journals, and defend a PhD thesis within 4 years.
The terms of employment are in accordance with the Dutch Collective Labour Agreement for Research Centres ("CAO-onderzoeksinstellingen"). The initial labour agreement will be for a period of 18 months. After a positive evaluation, the agreement will extended by 30 months. The gross monthly salary, for a PhD student on a full time basis, is €2,291 during the first year and increases to €2,937 over the four year period.
Employees are also entitled to a holiday allowance of 8% of the gross annual salary and a year-end bonus of 8.33%. CWI offers attractive working conditions, including flexible scheduling and help with housing for expat employees.
