"AlphaCode tackles the problem by generating over a million potential solutions for a single problem—multitudes larger than previous AI attempts. "As a sanity check and to narrow the results down, the AI runs candidate solves through simple test cases. It then clusters similar ones so it nails down just one from each cluster to submit to the challenge." The big question for me is, where did the test cases come from? They seem to be contributing much more to the outcome here than just "a sanity check and to narrow the results down." If they were effectively spelled out as part of the challenge, then this is an impressive result extending the trajectory of other recent achievements, but not so far as to justify the title's "conquers coding." If they were not, then this would seem to be taking things to a whole new level.
