I'll start with what I do not mean by this question. I know you need to know programming and data structures, but what I am asking about is specific algorithms and theorems.

The ones I can enumerate now (edited after some answers):

I'd love to learn about a Chinese Reminder Algorithm to stop forgetting so much stuff ;)

  • A* algorithm
  • honestly a lot of other graph algorithms, just be aware of them, and be able to find algorithms you didn't know before
  • OEIS
  • SMT solvers
  • set operations on intervals

I followed the link for Spectral Decomposition, and noped right out when I saw the banner "This article may be too technical for most readers to understand."

Great list though, thanks!

Not an algorithm or theorem, but specializing to the input is a good general tip to at least get an answer ime

In terms of algorithms: flood fill is useful, a few other graph algos like min-cut/max-flow come in useful sometimes.
