Tonicha is speaking at UW-Madison logic seminar

Our PhD student, Tonicha Crook, is giving a talk at UW-Madison logic seminar today at 3pm.


The Weihrauch Degree of Finding Nash Equilibria in Multiplayer Games


Is there an algorithm that takes a game in normal form as input, and outputs a Nash equilibrium? If the payoffs are integers, the answer is yes, and a lot of work has been done in its computational complexity. If the payoffs are permitted to be real numbers, the answer is no, for continuity reasons. It is worthwhile to investigate the precise degree of non-computability (the Weihrauch degree), since knowing the degree entails what other approaches are available (eg, is there a randomized algorithm with positive success change?). The two player case has already been fully classified, but the multiplayer case remains open and is addressed here. As well as some insight into finding the roots of polynomials, which is essential in our research. An in-depth introduction to Weihrauch Reducibility will be included in the presentation, along with a small introduction to Game Theory.

CCC 2020

A number of Swansea theory group members are attending the CCC 2020 (Continuity, Computability, Constructivity – From Logic to Algorithms) conference, taking place from 31 August to 4 September via Zoom. Their work will be presented in the following talks:

CCC conference series are linked to the CID project that Swansea University actively participates in the recent years. This year the conference features talks by a number of invited speakers:

Tonicha at CiE

Our PhD student Tonicha Crook attended her first CIE conference and gave an interesting talk on The Weihrauch degree of finding Nash Equilibria in multiplayer games.

25th International Workshop on Algebraic Development Techniques 2020

Today Swansea is hosting the first virtual WADT, and you are gently invited to participate.

The virtual WADT is part of the 25th International Workshop on Algebraic Development Techniques 2020, which hopefully will still happen as a physical meeting in autumn this year.   The algebraic approach to system specification encompasses many aspects of the formal design of software systems. Originally born as a formal method for reasoning about abstract data types, it now covers new specification frameworks and programming paradigms (such as object-oriented, aspect oriented, agent-oriented, logic and higher-order functional programming) as well as a wide range of application areas (including information systems, concurrent, distributed and mobile systems).

The workshop takes place under the auspices of IFIP WG 1.3.

Please see below for the programme.

Update on BCTCS2020

We remain hopeful that our conference will go ahead as planned. However, due to the uncertainty created by COVID-19, we are putting into place contingency plans.

Swansea University has procured a licence for a robust video-conferencing system (ZOOM) which we can use for the conference. If it becomes necessary, then a user would need to install this onto their computer. This system is free to install and use, the only cost is for Swansea as the licence holder. Of course, the computer would need to be connected to a webcam and microphone in order to participate fully in the conference – in particular, to deliver a lecture or to ask questions of the speakers.

Anyone who cannot come to Swansea due to the COVID-19 situation would have their fee reimbursed through eventbrite (as you won’t be requiring the catering). However, we really don’t want this to be an incentive to stay home; AlgoUK/BCTCS is first and foremost a net working event, so if it is possible, we are keen to welcome you in person.

We will keep you aware of any developments, and thank you for your patience and understanding as we do our best to ensure AlgoUK/BCTCS is as successful as it can be.
