Generative Artificial Intelligence Tools Policy
The technological world has changed beyond our wildest imaginations in recent years with the widespread access to generative artificial intelligence tools. Whereas this is mostly for the good, a small number of members have possibly been using it inadvertently in a manner that conflicts with the mis

Gauss–Seidel visually explained
An interactive demo of the Gauss-Seidel method for solving linear equation systems. When and why does it work? And why, when you flip the equations, it suddenly stop working? You can now play and see.
Private Status and Opting Out
Members have always had the option of making their accounts private, which means they will not appear in any public ranked tables, including the fastest solver tables. However, we have now provided an option which allows members to maintain public status, but opt out of individual fastest solver tab

MathJax Changes
The guide to formatting posts has always asked members to use single dollar for inline TeX content and double dollar for block level, but some alternatives were previously supported. For example, it was possible to use \[ and \] delimiters for block level and you were able to add TeX to the page dir

BBCode Update 2025
Over the years the BBCode module used in the problem threads has continued to be modified and have additional tags added. So, to ensure a more streamlined performance, the entire module has been rewritten. Every attempt has been made to support both recent and legacy posts and I have tried my best t

Why learn about the golden-section search
An interactive demo of bisection search and golden ratio search algorithms. There is also a motivation to learn them both. Spoiler alert! One converges better, and the other has a better computational cost.
Summer Break
The last problem of this academic year will be published on Saturday Aug 02 at 16:00 (UTC). The first problem of the new academic year will be published on Saturday August 30 at 19:00 (UTC).(Friday 06 June 2025: Summer Break)
A smooth and sharp image interpolation you probably haven't heard of
An image interpolation that gives us a continuous and smooth image, where every interpolated value only depends on the four neighboring pixel values. The image becomes smooth, but sharp features remain sharp.
The Real C++ Killers (Not You, Rust)
All the “C++ killers”, even these which I wholeheartedly love and respect like Rust, Julia, and D, help you write more features with fewer bugs, but they don't much help when you need to squeeze the very last FLOPS from the hardware you rent. As such, they don’t have a competitive advantage over C++

Rational interpolation
Rational interpolation is a step forward from polynomial interpolation towards rational splines. With rational interpolation, you can build functions that run through a set of points and also have vertical asymptotes whenever you want. With this capability, you can now model functions like logarithm

Understanding Convolutions on Graphs
Understanding the building blocks and design choices of graph neural networks.
A Gentle Introduction to Graph Neural Networks
What components are needed for building learning algorithms that leverage the structure and properties of graphs?
Distill Hiatus
After five years, Distill will be taking a break.
Adversarial Reprogramming of Neural Cellular Automata
Reprogramming Neural CA to exhibit novel behaviour, using adversarial attacks.
Weight Banding
Weights in the final layer of common visual models appear as horizontal bands. We investigate how and why.
Machine is now 2 and still running !
Guiness world record.
Recommissioning goes well
We've moved the machine. It's up and running, The end is nigh !
The Megaprocessor is moving to a museum.
The Megaprocessor will be moving to the "Centre for Computing History" in a few weeks time.
Open Days, reliability, ....
Next open day is 10 Sep.
Starting to get a feel for reliability
Looking at web traffic
Megaprocessor now on YouTube
Several people have remarked that the videos can be slow to play so they've all been uploaded to YouTube.
