The fact that there isn't a closed-form solution doesn't make it a complex mathematical problem.

Guessing a number isn't a complex mathematical number, it's just guessing a number.

afaik the solution that has to be "guessed" is not random. We just don't know how to get to it without brute force.

Brute-force solutions are still solutions :)
