His most ambitious contribution so far may be the Goedel machine (2003), a general problem solver which solves arbitrary computational problems in an optimal fashion inspired by Kurt Gödel's celebrated self-referential formulas (1931).
Schmidhuber writes that since age 15 or so his main scientific ambition has been to build an optimal scientist, then retire. First he wants to build a scientist better than himself (he says his colleagues claim that should be easy) who will then do the remaining work. He claims he "cannot see any more efficient way of using and multiplying the little creativity he's got".
