Wednesday 3rd July 2024 saw 30+ colleagues interested in Artificial Intelligence and Pathology descend on Warwick University’s TIA Centre to hold a workshop.

Delegates from a variety of disciplines, including pathologists and data scientists, attended the workshop, on Campus. The focus of the workshop was to explore the Future Interface of Computing and Pathology.

The meeting was lively and interactive and will be the first in a series of workshops that will be hosted by the TIA Centre in furtherance of this subject area. Thank you to all those who participated.

If you would like to join in future workshops please contact the TIA Centre at tia@warwick.ac.uk.

Six papers from the Theory and Foundations Research Group and the Centre for Discrete Mathematics and Its Applications (DIMAP) have been accepted to the 65th IEEE Symposium on Foundations of Computer Science (FOCS 2024), the flagship conference in theoretical computer science that will be held on October 27 - 30, 2024 in Chicago, USA:

A recent paperLink opens in a new window published by Dr. Ian MertzLink opens in a new window, a postdoctoral researcher in the Theory and Foundations (FoCS)Link opens in a new window research group and the Centre for Discrete Mathematics and its Applications (DIMAP)Link opens in a new window, has disproved a longstanding conjecture on the limitations of space-bounded computation.

For many years it had been believed that a function, known as Tree Evaluation, would be the key to separating two fundamental classes of problems: those computable quickly (P), and those computable in low space (L). Mertz, along with James CookLink opens in a new window of Toronto, builds on their earlier work to show a low-space algorithm for Tree Evaluation, thus refuting this belief. In particular, their technique has attracted attention for shedding new light on the power of space-bounded computation, suggesting novel approaches to age-old questions in complexity theory. They show that space can be used in surprising ways, with the same memory serving many simultaneous purposes.

The paper, which Mertz will present at the 56th Annual ACM Symposium on the Theory of Computing (STOC 2024)Link opens in a new window, has been invited to the special issue of SIAM Journal on Computing (SICOMP)Link opens in a new window for the conference. STOC is the main conference of the Association of Computing Machinery (ACM) and one of the two premier venues for theoretical computer science, with only the top results being invited for publication in the special issue.

Mertz has also presented this work at many venues, including the Institute for Advanced Study (IAS), Columbia University, Oxford University, Warwick (Online Complexity Seminar)Link opens in a new window, McGill University, and others.
