🖥️ The Exit Algorithm:
Given the INPUT (the board) and the RULES, determine whether you:
• Can reach the EXIT.
• Conclude that no valid path to the EXIT exists.
Don't assume the correct path is the obvious one. You may find a solution that seems counterintuitive, as long as it never violates the RULES.

Well, this is amazing. this sequence converge to a irrational number... The proof is even amazing.

This is interesting
There are many ways to kill performance in a multithreaded program. My favorite one is false sharing, because you can get 10x performance just by moving some bytes around. So let's look into it.
