1. For a multi-state space, a method of propagating a first function, which is defined over a first state, to a second state, the method comprising:

  • a) identifying vectors to project from at least some points on the first state that serve as locations of inflection points in the first function;

    wherein the vectors are identified based on a model that penalizes measurements in certain directions more than other directions;

    b) based on the projected vectors, computing the second state from the first function.
