of the Rubik's cube
Friday, August 17, 2007

Remember the Rubik's Cube? That little box of multi-coloured squares
that you could only complete by carefully steaming off all of the
stickers and then re-sticking them in the right positions?

A team of US scientists has used a powerful number-crunching
supercomputer to work out that the minimum moves needed to complete a
Rubik's Cube from any starting position, is 26, one less than the
previous record.

In reaching this figure Daniel Kunkle and Gene Cooperman from
Northeastern University in Boston developed algorithms that can be
useful for all kinds of different applications from scheduling air
flights to determining how proteins will fold.
