2026-03-03 19:10:18 +0100 <c_wraith> absolutely the best lesson to take from that, yes

2026-03-03 19:05:30 +0100 <EvanR> this is why it's better not to look at academic research and reinvent everything from the wheel. No way to know if the paper's right!

2026-03-03 18:57:48 +0100 <c_wraith> There were actually two bugs in those libraries. One was that they tried to optimize inserting to an empty tree and got the logic wrong so that it didn't balance repeated insertions on the same side. The other was that the paper they were working from misread one of its references and so missed an important part of the balancing algorithm's weight comparisons.

2026-03-03 18:12:52 +0100 <c_wraith> I feel relatively competent addressing its balancing algorithm, because it's the same one used in the priority search pennants a couple different libraries used that I ended up spending a lot of time investigating a year ago after my AoC solution to one problem found a balancing error.

2026-03-03 18:06:11 +0100 <c_wraith> (the proof that it's correct is complicated, but the algorithm is simple)
