Rubik's cubes (Johan de Ruiter) | Discuss about this problem |
Find the hardest possible N*N*N Rubik's cubes. Two parts contest: one part to submit your cubes to solve, and one part to solve the submitted cubes. First part: submit several hard-to-solve cubes for every NxNxN per participant Second part: solve all submitted cubes in the minimum number of rotations (half or quarter turns may give us 2 subparts) |
