I used to be able to do it, don't know if I would remeber the pattern of moves now.

I used to know the patterns, but have forgotten them. I just put “How to solve Rubik’s cube” into a search engine. The answers are out there, if you want them. E.g. http://jeays.net/rubiks.htm

My 15 year old takes 1min 20 seconds to get it done.

Some people understand recursion better than others. Maybe this definition will help:

Recursion
If you still don't get it, See: "Recursion".

Re: Rubik's Cube
 

haven't touched one in years but i used to be consistent in the 30 - 45 second range. that was back in the 80's ...

once you get the hang of it, they're simple to solve ...

I can do them in 10 seconds blindfolded.


Then I wake up.

Wow, 3 years ago...time goes so fast.

Guys,
Step 1: Choose a top color. Keep the center-cubelet that matches this color on top at all times.
Top Layer:
Step 2: Solve the top-layer edges.
Step 3: Solve the top-layer corners.
Middle Layer:
Step 4: Solve the middle-layer edges.
Bottom Layer:
Step 5: Orient the bottom-layer edges.
Step 6: Position the bottom-layer edges.
Step 7: Position the bottom-layer corners.
Step 8: Orient the bottom-layer layer corners.
Step 9: Done

I saw a 6 axis articulated robot with vision solve one at the Assembly Tech trade show. The rep gave you the cube and allowed you to mix it up. He took it and put it in the robots end-effector, the robot scanned it and on a screen it told you how many moves it would take to solve it. Flawless everytime! In the same booth they had two robotic hands playing a Chopin piece on a keyboard. The company was Panasonic and that was 10 years ago!

Just in case the old 3x3 is too easy for you.....

30 years ago, my ex brother in law had one and managed to get one side done...took him forever. I remember he claimed he couldn't imagine anyone doing the whole thing. He left for work. I noodled around with it for about half an hour then just peeled the stickers off and "completed" two sides. I tossed it on his bed and left.

A couple of days later he wanted me to show him how I'd done it and I said I didn't know, he'd just have to keep fiddling with it. Of course I had screwed it up forever and it was now impossible to EVER make it work. At the time I felt regret but never told him. 20 years later he contributed to my screwing at the hands of his sister, my soon to be ex and I felt a LOT better for hosing him on the Rubik's cube!

Broke mine taking it apart.
:rolleyes:
