Easiest to code algorithm for Rubik's cube?

Question

What would be a relatively easy algorithm to code in Java for solving a Rubik\'s cube. Efficiency is also important but a secondary consideration.

Answer 1

The simplest non-trivial algorithm I've found is this one:

It doesn't look too hard to code up. The link mentioned in Yannick M.'s answer looks good too, but the solution of 'the cross' step looks like it might be a little more complex to me.

There are a number of open source solver implementations which you might like to take a look at. Here's a Python implementation. This Java applet also includes a solver, and the source code is available. There's also a Javascript solver, also with downloadable source code.

Anthony Gatlin's answer makes an excellent point about the well-suitedness of Prolog for this task. Here's a detailed article about how to write your own Prolog solver. The heuristics it uses are particularly interesting.
