How many times have you gotten an algorithm to work, where later you realize you had an off by 1 error, or a double free somewhere in your code that you didn’t catch until you exposed your program to more situations? I am curious about how they validated the ML approach. The advantage of simulation is the ability to uncover emergent phenomena that are difficult to predict and are not expected. It could be that they’re averaging a lot of common situations and they may miss novel outcomes.
