The wiki page you linked is almost entirely about the abstract mathematical definition and talks about algorithms only for a single paragraph, which is about computational complexity. If you look at the wiki page for a particular algorithm (e.g. Strassen: https://en.wikipedia.org/wiki/Strassen_algorithm) then of course they talk about stability in comparison to the naive algorithm (although the page could be improved quite a bit). If your college textbooks do not mention…</p><p><a href="https://hackerpaper.kaipfister.de/p/math_0603207/">Paper and discussion history</a>. A mention is not an endorsement.</p>math.NA
