1. A method comprising:

  • receiving a plurality of current observations about a real or simulated world, wherein each of the current observations is received from a different one of a plurality of different types of physical sensors;

    maintaining, by a computational unit, an objective;

    representing the objective using an incremental cost of a plurality of potential actions;

    maintaining, by the computational unit, a current uncertainty about an unknown state of a world, wherein the current uncertainty is represented by one or more probabilities of a plurality of high-level explanations of the world, such that a set of possible explanations at any one time is sparse, and wherein the current uncertainty is updated from the plurality of current observations using a filter comprising a sparse network;

    determining, by the computational unit, one or more optimal actions to achieve the objective with an optimized expected total future cost, wherein said determining comprises performing both backward induction on the optimized expected total future cost and forward induction on the current uncertainty about the unknown state of the world; and

    performing, by a physical actuator, the one or more optimal actions.
