An algorithm is not a monolithic thing. There are probably thousands of algorithms here. I would wager a guess that there are hundreds of duplicated algorithms in this, and also wager that they are not exactly the same.
This is software that from what I see was never really tested. Just a “that sounds about right”. Last minute changes to correct a small bug without good testing is just the ticket to drain the World Economy of Trillions of dollars. There was no vetting, it was impossible.
Software is all about details, details. One small detail can literally wreck a whole application.
Evidently you never get the same result twice with this thing which should tell you something.
This software WRECKED a 20 trillion dollar economy just in this country, not accounting for the rest of the world. No one should be defending it on any level.
