Hi to everyone
I´m a rubix cube researcher in the last 15 years and i found that the challenge is pure math.
I wondering if anybody has researched by this point of view. I would appreciate replies to this topic.
sincerely,
Alessandro Oliveira

I don't know if it has to be in hard.
If you are not interested in shortest solving the ABA-1B-1 is the general trick for permutational puzzles (as it is usually much more simple than either of A and B).
If you are looking for shortest solutions iterative deepening with good heuristics lower bound helps.
If you are looking for human suitable algorithms as fast as possible ... build in order to limit movements as slow as possible (avoid undoing as long as it is possible) ... so start from 3 edges and put the corner among them to build 2x2x2 block, continue to 2x2x3 ... the rest is not that much clear ... and it depends how much memorisation you sacrifice ...

the mathematics of Rubik's cube is discussed. Maybe that is a better place to chill.
