Optimal Ordered Problem Solver (OOPS):Get rid of the constants! (Schmidhuber, 2002)
Bias: task-dependent probability distribution on programs
Task-specific prefix codes: execute program prefixes while generating them; prefixes modify task-specific internal states & request their own prolongations & compute probabilities of their possible continuations.
prefix pn solves first n tasks; stored in non-modifiable memory; may call or copy-edit previous pi (i<n).
