New, brief overview of lexicase selection: lexicase.ai
It considers individual training cases in different random orders, and therefore with different priorities, for each selection event.

In my first interaction with ChatGPT 5 it provided four "key references," every one of which was hallucinated or broken in one or more ways. This was about a machine learning techique for which there is a lot of information online, and it totally butchered it.
