To summarize; The guy built a random cpu instruction generator for x86. An instruction can be at most 15bytes long. So, the solution space is quite huge. He cut the solution space to 100k by generating them with DFS style fashion and validating them through cpu exceptions and flags. In the end, there's kind of map reduce style distiller to analyse hidden and valid instructions. Nice job though
