omega

·

A hypothetical super-intelligent being used in philosophical problems. Omega is most commonly used as the predictor in Newcomb's problem [? · GW]. In its role as predictor, Omega's predictions occur almost certainly. In some thought experiments, Omega is also taken to be super-powerful.

Omega can be seen as analogous to Laplace's demon, or as the closest approximation to the Demon capable of existing in our universe.
