The Algorithms and Complexity group is concerned with the development and analysis of efficient algorithms for hard computational problems that arise in practical applications, as well as the establishment of theoretical limits of algorithmic approaches.
In particular, the group consider problems arising in the areas of Combinatorial Optimisation, Artificial Intelligence, Automated Reasoning, Planning and Scheduling, Network Design, Cutting and Packing.
Among the methods the group's research builds upon are mathematical programming techniques, satisfiability solving techniques, dynamic programming, graph algorithms, metaheuristics, fixed-parameter algorithms, and constraint-based methods.
