Re: [sub-project] Perfect cuboid

But not every diagonal will be checked, but only those, who are a product of 4k+1 primes. Do you feel a difference? Not a real difference, up to n there are O(n/sqrt(log(n))) such numbers, this is a theorem. That gives you still need to check O(X^2/sqrt(log(X))) different $g$ values to check all od...

Re: [sub-project] Perfect cuboid

So, I've finished my idea description. Any questions, proposals, objections? I read your algorithm, that's correct. The problem with that g can be very large. If you fix X, where X is the odd term of {a,b,c} then you can only say that a,b,c<=(X^2-1)/2 (I read this bound, the X^2-1 bound is trivial)...

Re: [sub-project] Perfect cuboid

I can host the project in yoyo@home and will take care of - wu-generation - validator - assimilator The only thing we need is a C/C++ app without any gui and optional: - checkpoints - progress indicator yoyo Hi! Worked some days on this nice problem. My code would search also for Euler bricks! If y...
