Optimization is an easy trap to step in. You can take it up in other layers aswell, optimizing your choices about the choices to optimize | Ad infinitum.

At some undefined point you may realize that you are trying to solve an undecideable problem. You can spend an infinite amount of time, and not get an answer.

You cannot build an algorithm to determine the amount of time that an arbitrary problem can be solved in, or if it's solvable in the first place. You must make a choice based on imperfect knowledge.
