🖥️ 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.
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.

Hilbert swung so much to the other extreme as to not take consistency of the theory of with one constant-symbol 0 and one function-symbol S and only two axioms (S(x)≠0, S(x)=S(y)→x=y) for granted, in partc. rejecting the true-in-the-standard-model-argument!

Here is one: synthetic methods or exact algebraic results are preferred.
