Barry Schwartz 🫖I have made a minor update to my ATS/Postiats ITP rootfinder at https://github.com/chemoelectric/ats2-itp-rootfinder
ITP rootfinding is a more recent alternative to the Brent rootfinder of the 1970s that you still see everywhere. The Brent rootfinder works fine, but I switched to the ITP when it was published.
