This is from a Yahoo article on Rubik's Cube:

One may suppose God would use a much more efficient algorithm, onethat always uses the shortest sequence of moves; this is known as God'sAlgorithm. The number of moves this algorithm would take in the worstcase is called God's Number. At long last, God's Number has been shown to be 20."

The research, published online, ends a 30-year search for the mostefficient way to correctly align the 26 colored cubes that make up Erno Rubrik's 1974 invention.

"It took fifteen years after the introduction of the Cube to find the first position that probably requires 20 moves to solve," the team said. "It is appropriate that fifteen years after that, we prove that twenty moves suffice for all position."

Those who run the lotteries love it when players look for consistency in something that's designed not to have any.

Lep

There is one and only one 'proven' system, and that is to book the action. No matter the game, let the players pick their own losers.

    If God is that calculated in his decision making, why is his creation filled with many irrational equations?

      who know's, maybe God would take his time with it as well.  not sure the fewest moves is the best algo.

        like 1 week ago i was going to post that you could/can win the lottery with the rubik´s cube but is only if you are trying to win with 1 ticket and is more complex you will need like a supercomputer even though now that i think about it you could retrace the position of the bouncing balls per second...

        the way it works is that if you let the bouncing balls machine be like a rubik´s cube and each small cube of the rubik´s cube be the position of the bouncing balls in time per second you could trace it all back and create a mathematical formula...But the reason why i didnt write it is because nobody chases Mega Millions/PB to win it with 1 ticket nobody does that anymore unless they have sufficient time in their hands or unless a computer/mini supercomputer was doing the job for them....

        Eventually people will quit their paper and pencil workouts for the lottery and use computers...is a fading science/method...

        The Forex trades: 1.6 Trillion dollars EVERY day, that´s more than the GDP of the Carribbean Central America, COMBINED. Enough to feed every crook out there for centuries...To all Geniuses & Powers Countries of the World the Planet needs breakthroughs in all Medicine, Veterinary, Biology related fields, Psychology, Population Psychology/Sociology..They need to genetically ingeneer new plants species/types to give more variety of plants and thus have more resources for combating diseases¨

          Anybody can play with a Rubik's Cube, but only some can solve it. Using the fewest moves possible is clearly the best algorithm if your goal is simply to solve it. That's not to say there aren't other interesting solutions, such as using as many moves as possible without repeating a position or recreating a previous pattern, or the fewest moves to finish successive colors.

            The thing is that if Claude Shannon hadn't died of Alzheimer in 1978, we probably would've had not only the number but the solution simply defined back then.   His last unpublished paper was on the Rubik's Cube.

                ANYONE can solve it.

                Approx 100 moves? He moves pretty fast, hard to keep count.

                  Are you serious or making a joke?  The cube is 3x3x3 and he only moves two of the 3x3 surfaces. That leaves a 2x2x3 section that doesn't get changed at all. It only "works" because that part of the cube was already done.

                    Not making a joke (this time).

                    The video simply demonstrates that the cube can be done by anyone without any skill.  It's not an optimal solution.  Sure the original section is not changed - but that could be true no matter what method you use to solve it.  Not sure why that matters if the colors all end up where they belong?

                      The point is that the four squares on the lower right remained stationary throughout all the moves, had they not already been what they should be, the two moves would not have been able to cycle the wrong squares out and the right squares in.   Perhaps if the method involved rotating the entire cube as well but then would it actually sequence through all possible combinations rather than find a short loop.

                      Not only is it not an optimal solution, it's only a solution for a very specific configuration involving the cube already being partially solved.   I don't doubt that the cube can be solved without skill but not by those two moves.   Give it a try, scramble a cube and try those two moves.

                          I was never interested in a Rubik's cube and haven't seen one in years.  So, can't give it a hands-on try.

                            pumpi, I think you are 100% correct!  And if I had the answer to that, people would make out a check to me for $1 Million to $1 Billion per year!
