Intro to Algorithms
- Elementary data structures
- Sorting, graphs and dynamic programming
- Modelling computational problems
- Algorithm performance and analysis
In May 2026 I began a project to refamiliarise myself with some of the mathematics I haven’t touched since university. My intent is to get to grips with these subjects at the structural/conceptual level as much as the practical.
As such I’ve selected these courses to be interlocking, rigorous and free. You can assume that I strongly recommend any of the courses I’ve completed.
Lecture notes/problem sets are written by hand on a Remarkable2, then synced, compressed, and uploaded to Drive via cron job. From there they’re part of the regular content pipeline. Also, this has been a chance to get back to writing Python, so I’ve linked repos where relevant.
