RNA secondary structure Updated 2025-07-16
Analogous problem to the secondary structure of proteins. Likely a bit simpler due to the strong tendency for complementary pairs to bind.

GitHub's replacement of
master branch with main (2020) Updated 2025-07-16By GitHub around Black Lives Matter, due to a possible ludicrous relationship with slavery of black people:

Undecidable problem Updated 2025-07-16
Or in other words: there is no Turing machine that always halts for every input with the yes/no output.
Every undecidable problem must obviously have an infinite number of "possibilities of stuff you can try": if there is only a finite number, then you can brute-force it.
Lists of undecidable problems.
Coolest ones besides the obvious boring halting problem:
There are unlisted articles, also show them or only show them.
