After a year and a half of no forward progress, I'm finally regaining interest in Project Euler, which is a series of programming/problem-solving/math challenges. As the Project Euler FAQ puts it:
Project Euler is a series of challenging mathematical/computer programming problems that will require more than just mathematical insights to solve. Although mathematics will help you arrive at elegant and efficient methods, the use of a computer and programming skills will be required to solve most problems.
Obviously, if I have a question about the programming required to solve a PE challenge, it belongs on Stack Overflow. Similarly, if I have a question about the mathematics underlying the challenge, I should be asking it on Math.SE. But what if I have a question about the process of solving a challenge?
For example, here is the actual question I was considering asking, which led to this meta question:
Should I just brute-force Problem 11?
Other than checking to see if any of the four digits in the equation are zero, I don't see any good way to avoid calculating the product of each 4-item sequence in the block. Is brute force the 'right' solution, or should I be looking deeper? Problem 11 is pretty early on, I don't know if I'm making things harder than they need to be.
The Gaming FAQ says "puzzle solving" questions are on-topic, and I think Project Euler is probably a game (because I can't think of an argument that disqualifies Project Euler which doesn't also disqualify SpaceChem), so...
Are Project Euler questions that relate to the process of solving the puzzles on topic?
