That is interesting. Asking as a complete ignoramus - is there not a way to do this now? Like start off with a 100 of reagent and at every step use a bit and discard if wrong

But for every step that turns out to be "correct" you now have to go back and redo that in your held-out sample anyways. So it's not like you get to save on repeating the work -- IIUC you just changed it from depth-first execution order to breadth-first execution order.

??? What's up with native English speakers and random acronyms of stuff that isn't said that often? YMMV, IIUC, IANAL, YSK... Just say it and save everyone else a google search.

That likely ends up with 100 failed results all attributed to the same set of causes
