On December 12, 2022, we held the DIMAP Theory Day 2022. This event highlighted recent, exciting advances in the field of Algorithms and Complexity and provided means to facilitate interactions within the algorithms research community in the UK. The event was supported by the Centre for Discrete Mathematics and its Applications (DIMAP) and UKRI. We plan to hold further events in this series on a regular basis.

The University of Warwick will be hosting the Seventh Workshop on Algebraic Complexity Theory (WACT) from March 27 to March 31, 2023.

Algebraic Complexity Theory is a vibrant field that has been seeing a tremendous amount of activity in the recent years. Its classical questions have been interwoven with deep questions from algebraic geometry, invariant theory, and representation theory. Researchers study a wide range of interlinked topics: arithmetic circuit lower bounds, algorithmic algebra, algorithmic invariant theory, geometric complexity theory, tensor rank, polynomial identity testing, and polynomial reconstruction, to name a few. The workshop brings together experts from different parts of this rich field to discuss the current state of the art, discover new connections, and set the directions for the future.

Numerical simulations and visualizations developed by researchers from the High Performance and Scientific Computing (HPSC) group at Warwick’s Department of Computer Science in collaboration with Rolls-Royce, PPCU Hungary and Universities of Surrey and Birmingham has won the award for the best Visualization in the Scientific Visualization and Data Analytics Showcase at the 2022 Supercomputing (SC) Conference, held in Dallas TX. SC is the premier international conference on supercomputing providing a major forum for presenting the highest level of accomplishments in high-performance computing, networking, storage, and analysis. It is held annually in the US and attended by over 10000 attendees from all over the world.

Numerical simulations and visualizations developed by researchers from the High Performance and Scientific Computing (HPSC) group led by Dr. Gihan Mudalige at Warwick’s Department of Computer Science in collaboration with Rolls-Royce, PPCU Hungary and Universities of Surrey and Birmingham have been selected as one of the six finalists for the Scientific Visualization and Data Analytics Showcase at the 2022 Supercomputing (SC) Conference, held in Dallas TX. SC is the premier international conference on supercomputing providing a major forum for presenting the highest level of accomplishments in high-performance computing, networking, storage, and analysis. It is held annually in the US and attended by over 10000 attendees from all over the world. A video regarding the work can be found here.

Congratulations to Harita Dellaporta for receiving the Best Paper Award at the premier conference in Artificial Intelligence and Statistics (AISTATS) 2022 for her paper on Robust Bayesian Inference for Simulator-based Models via the MMD Posterior Bootstrap.

We are delighted to announce that Peter Kiss, a PhD student in the Theory and Foundations Research Division, has won the Best Student Paper Award at the Innovations in Theoretical Computer Science (ITCS) 2022 conference for his single-author paper on "Deterministic Dynamic Matching in Worst-Case Update Time". Computing a maximum matching in a graph is one of the most fundamental problems in design and analysis of algorithms. The paper makes important progress on this problem in a setting where the input graph is changing over time via a sequence updates, and one wishes to maintain a large matching efficiently in such a dynamic graph. Along the way, the paper develops a general purpose technique for converting any dynamic algorithm with amortised update time into one with worst-case update time, provided the initial algorithm is able to handle a more general form of batch updates.

Members of the High-Performance and Scientific Computing Group (HPSC) at the department of Computer Science has won a best paper award at the 28th IEEE International Conference on High-Performance Computing, Data and Analytics held on the 17th-18th of December. The winning paper titled Predictive Analysis of Large-Scale Coupled CFD Simulations with the CPX Mini-App, develops a novel representative (mini-)application, specifically designed to model coupled execution of multi-physics numerical simulation codes from the CFD domain. The mini-coupler, CPX, is the first of its kind, combining multiple CFD mini-app instances to predict the run-time and scaling behaviour of large scale coupled CFD simulations, on modern multi-core and many-core clusters such as used for production turbomachinery design at Rolls-Royce plc. The work was carried out by PhD candidate, Archie Powell, in collaboration with Kabir Choudry, Arun Prabhakar, and Gihan Mudalige at the Department of CS Warwick, Dario Amirante (University of Surrey), Istvan Reguly (PPCU) and Stephen Jarvis (University of Birmingham).

The work was funded by the EPSRC Prosperity Partnership in Computational Science for Advanced Simulation and Modelling of Engineering Systems (AsiMoV) and Rolls-Royce plc.
