Application-Driven Benchmarking of the Traveling Salesperson Problem: a Quantum Hardware Deep-Dive
The potential analysis of the capabilities of quantum computing, especially before fault tolerance at scale, is difficult due to the variety of existing hardware technologies with a wide spread of maturity. Not only the result of computations, but also the very process of running quantum-enhanced algorithms differ from provider to provider. The study includes a comparative analysis of various hardware architectures with the example of the Traveling Salesperson Problem, a central class of combin…

A min-max variational approach to the existence of gravity water waves
We establish the existence of gravity water waves by applying a mountain pass theorem to a singular perturbation of the Alt-Caffarelli functional associated with the two-dimensional water wave equations. Our approach is formulated entirely in physical coordinates and does not require the air phase to be connected, nor does it rely on symmetry or monotonicity in the $x$ or $y$ directions. The framework presented allows for both a variational approach to a variety of fluid equilibrium problems an…

Identifying the Smallest Adversarial Load Perturbations that Render DC-OPF Infeasible
What is the globally smallest load perturbation that renders DC-OPF infeasible? Reliably identifying such "adversarial attack" perturbations has useful applications in a variety of emerging grid-related contexts, including machine learning performance verification, cybersecurity, and operational robustness of power systems dominated by stochastic renewable energy resources. In this paper, we formulate the inherently nonconvex adversarial attack problem by applying a parameterized version of Far…

Infinite-order rogue waves that are small (but not small in $L^2$)

Infinite-order rogue waves that are small (but not small in $L^2$)
General rogue waves of infinite order constitute a family of solutions of the focusing nonlinear Schrödinger equation that have recently been identified in a variety of asymptotic limits such as high-order iteration of Bäcklund transformations and semiclassical focusing of pulses with specific amplitude profiles. These solutions have compelling properties such as finite $L^2$-norm contrasted with anomalously slow temporal decay in the absence of coherent structures. In this paper we investiga…

Content warning: BiCon coming up, Fri 25 to Sun 27 July 2025, Nottingham and online

BiCon comes to Nottingham this Friday!
It's a masking-friendly, though not mask-required, event, in a venue which is said to be pretty good for air quality.
There's also an online-only option, which I went to myself last year when the in-person side wasn't in Nottingham. We had a nice little group being companionable on the Zoom, with some of the in-person sessions running as hybrid.
You don't have to be bi to go - just bi-friendly and trans-inclusive. Typically it does include some non-bi people who just like the vibes :-)
Sliding-scale admission prices:
- in-person weekend tickets £65 down to £20
- in-person day tickets £40 down to £10
- online weekend tickets £20 down to £4.
Venue this year is two of the buildings belonging to the girls' high school, in between the Forest and the Arboretum. Nearest tram stop is High School. Nearest bus lines are brown, green, yellow, and purple.
There's usually a variety of session options in the day: some talky and some not; some bi-themed, some unrelated. In the evenings there'll be social space. Some people will go and march as a group in Notts Pride on the Saturday. I'm going to host an online pre-meet on the Wednesday evening.
Myself I've booked for the weekend, but in reality I might only make it to the online-Wednesday-pre-meet and the Friday, esp if I do go to Notts Pride on the Saturday. I might be all used up by Saturday night. (Even pre-covid I might've run out of steam by then :-) ) But if I didn't come in on the Sunday, I probably would still join in at least a little bit online.
More below on what I'm planning to contribute!
Feel free to ping me if you have questions :-)
