Part one of a new series on cognitive biases: why this one sits underneath all the others. What exactly is confirmation bias?

Tabu Search, Live

Part 9 of my Algorithms, Live series. A search algorithm that escapes dead ends by remembering them instead of rolling dice: it bans the moves it just made, even when they look best. Solve N-Queens in your browser with it here:

Why do spam emails try to trick us, in 2026, with McAfee antivirus scams?

Is my AOL account infiltrated?

Were my MSN account details leaked?

Will I receive a CD-ROM in the mail with 100 free hours of internet?

Genetic programming evolves the program itself. Watch a population of expression trees breed a formula that fits a hidden curve, live in your browser. Part 8 of Algorithms, Live.

Differential evolution has no step-size setting. Each move is the gap between two of its own population members, so the steps shrink as the population closes in. Part 7 of Algorithms, Live.

Most optimisers crawl along a long, thin, tilted valley because every step they propose is the wrong shape. CMA-ES watches which directions keep paying off and restretches its search cloud to match. Circle, tilt, needle. Part 6 of Algorithms, Live.

In 2021 we turned Factorio into an optimisation benchmark: a real game, driven by a real optimiser, scored on what came out the other end.

You can now run that problem in your browser. Watch two algorithms lay belts across a walled grid and argue about which one is smarter.

How it works, and the one place I cheated on my own architecture:

My website is static. No server, no database, nothing running.

It still knows what I'm reading and what I played last.

A robot commits to the repository every Monday at 6am while I sleep.

Variable neighbourhood search was the algorithm in my first published paper, back in 2016.

I have rebuilt it as something you can run in a browser.

In 1995 a social psychologist and an electrical engineer sat down to animate a flock of birds.

They deleted rules to see which mattered. Collision avoidance went. Velocity matching went.

What was left could not fool a pigeon. But it could find the optimum of anything.
