Eternity II

Its a puzzle with a 2M$ prize to the first solver.
There's a smaller demo version on the site.

Couldnt a computer solve this relatively quickly? Or are there too many combinations?

Seems a brute force edge matcher would work decently.

I solved the 4*4 demo so I could post it if someones interested.

Well the main puzzle is significantly harder. It would take hundreds of years to solve it with brute force with todays best computers...

got it 4:10, i think i got lucky though.

4x4 was 2:15 i think for me.

This has to be a computing power thing...

Interesting...

There's 256 pieces, which can be arranged in 256 factorial ways. That's a huge number - my windows calculator shows it's 8.6x10^506.

It's actually a bit smaller because the corner and edge pieces can only be placed certain way.

But then again, all pieces can be rotated.

I think the formula for 256 pieces that can be rotated 4 ways that do NOT have borders and corners is 4^256 x 256! = 10^661 or so.

That number of combinations is, of course, impossible to compute.
