ACiD, Algorithms and Complexity in Durham, is a world-leading research group with research programmes involving many international collaborators. Theoretical Computer Science comprises the development of algorithmic techniques that efficiently exploit the power of modern computers, the study of the limits of computation and the ways in which we can cope with, and take advantage of, intractability, and the science of the unsolvable.

The group is broad-based with research foci including computational complexity, proof complexity, descriptive complexity, graph theory, exact algorithms, randomised algorithms, approximation algorithms, parameterized algorithms, finite model theory, constraint satisfaction, interconnection networks, universal algebra and mathematical logic.
