Improved algorithms via random sampling. Randomized methods have recently come into the spotlight when it comes to solving computationally "intractable" subset problems. The running time of a range of algorithms has been improved by replacing their first steps by a simple method of adding to the solution a small subset uniformly at random, and repeating the process many times. This project will explore various other ways how (not necessarily uniform) random sampling can improve the running time ....Improved algorithms via random sampling. Randomized methods have recently come into the spotlight when it comes to solving computationally "intractable" subset problems. The running time of a range of algorithms has been improved by replacing their first steps by a simple method of adding to the solution a small subset uniformly at random, and repeating the process many times. This project will explore various other ways how (not necessarily uniform) random sampling can improve the running time of algorithms; and explore the analysis of polynomial-time randomized algorithms. The project will focus on cycle cutsets and domination problems that have applications in operating systems, chip design and verification, facility location, and surveillance and monitoring.

Tractable topological computing: Escaping the hardness trap. Computational topology is a young and energetic field that uses computers to solve complex geometric problems driven by pure mathematics, and with diverse applications in biology, signal processing and data mining.

Computational topology is a young and energetic field that uses computers to solve complex geometric problems driven by pure mathematics, and with diverse applications in biology, signal processing and data mining. A major barrier is that many of these problems are thought to be fundamentally and intractably hard. This project aims to defy such barriers for typical real-world inputs by fusing geometric techniques with technologies from the field of parameterised complexity, creating powerful, practical solutions for these problems. It is expected to shed much-needed light on the vast and puzzling gap between theory and practice, and give researchers fast new software tools for large-scale experimentation and cutting-edge computer proofs.Read moreRead less
