> NP-hard I wrote a toy compiler once as an educational project. I accidentally invented super-optimization, too. Felt so clever for a whole hour or so. It was guaranteed to produce the optimal program that can be represented in the intermediate representation I used. Unfortunately, this only works for programs with up to six operations with current hardware; more than about ten would require more RAM than can fit in the universe. Finding shortcuts to prune down that problem is the black art of practical optimization.
