Postdoc Position in Computer Science Focused on SAT Solving

The Theoretical Computer Science Group at KTH Royal Institute of Technology invites applications for one postdoc position in computer science focused on SAT solving.

Job Description

The Theoretical Computer Science Group at KTH (www.csc.kth.se/tcs) offers a strong research environment spanning a wide range of research topics such as complexity theory and approximation algorithms, computer and network security, cryptography, formal methods and natural language processing. We have one of Europe's most prominent groups in algorithms and complexity theory, and the research conducted here has attracted numerous international awards and grants in recent years.

The postdoctoral researcher will be working in the research group of Jakob Nordström. Much of the activities of this research group revolve around the themes of efficient algorithms for satisfiability in propositional logic (SAT solving) and lower bounds on the efficiency of methods for reasoning about SAT (proof complexity). On the practical side, one problem of interest is to gain a better understanding of, and improve, the performance of current state-of-the-art SAT solvers — in particular, solvers using conflict-driven clause learning (CDCL). We are even more interested in exploring new techniques that hold out the theoretical possibility of exponential improvements over CDCL, but seem hard to implement efficiently in practice, e,g, algebraic methods such as Gröbner bases or geometric methods such as pseudo-Boolean solving (basically 0/1 integer linear programming).

The research project is financed by a Breakthrough Research Grant and a Consolidator Grant from the Swedish Research Council and a Starting Independent Researcher Grant from the European Research Council. A more detailed description of the project can be found at www.csc.kth.se/~jakobn/project-proofcplx. The group currently consists of two postdoctoral researchers and four PhD students (in addition to the PI). There are also several other professors, postdocs, and PhD students in the TCS Group working on other aspects of algorithms and computational complexity, and so this is a unique opportunity to explore new connections between theoretical and practical areas of computer science within a vibrant and growing research environment.

Within the overall framework sketched above, the postdoc will be expected and encouraged to contribute to and influence the research agenda. Taking part in teaching graduate seminar courses is encouraged but not required. Travel funding is included, and the group also receives short-term and long-term visitors on a regular basis.

This postdoc position is a full-time employed position for one year with a possible one-year extension. The expected starting date is in August-September 2017, although this is to some extent negotiable.

This is an additional announcement on top of the postdoc position D-2016-0872 due to additional research funding. Candidates who already applied for the position D-2016-0872 should not apply again — all applicants for both announcements are evaluated in parallel.

Qualifications

Applicants should have or be about to receive a PhD degree in a subject relevant for the research area, and should have a passionate interest in research. The successful candidate is expected to have a solid background in computer science in general and SAT solving in particular, and preferably also mathematics, and should have a strong research record as witnessed by publications in conferences such as AAAI, IJCAI, SAT, CP, or similar, or in journals of a comparable quality. Problem solving skills and creativity are a must. Excellent programming skills are crucial.

The working language of the TCS group is English, and knowledge of English is also fully sufficient to navigate life in Sweden in general. It might also be worth mentioning that Sweden routinely scores at the absolute top in rankings of quality of life such as, e.g., the OECD Better Life Index.

Workplace

KTH Royal Institute of Technology in Stockholm has grown to become one of Europe's leading technical and engineering universities, as well as a key centre of intellectual talent and innovation. We are Sweden's largest technical research and learning institution and home to students, researchers and faculty from around the world. Our research and education covers a wide area including natural sciences and all branches of engineering, as well as in architecture, industrial management, urban planning, history and philosophy.

The School of Computer Science and Communication at KTH (KTH CSC) is a premier research and education institution in information technology, with activities at both KTH and Stockholm University. We conduct education and research in both theoretical and applied computer science. Our activities in theoretical computer science range from theory building and analysis of mathematical models to algorithm construction, implementation and simulation. Applied computer science covers a wide spectrum including computer vision, robotics, machine learning, high performance computing, visualization, computational biology, neuroinformatics and neural networks, and speech and music communication. We also conduct applied research and training in media technology, human-computer interaction, interaction design and sustainable development. For more information, see www.kth.se/en/csc.
