Solving a Rubik’s Cube with more squares than the original toy requires fewer moves than expected. A new algorithm developed by MIT computer scientist Erik Demaine and colleagues spots situations in which several squares can be put in place at once with a few simple twists. This efficient strategy outperforms the usual approach for solving supersized cubes — which concentrates on one square at a time — and challenges the prediction that the minimum number of moves needed is proportional to the number of squares on one side, the researchers report online June 28 at —Devin Powell
