1. An expert system including:

  • a memory for storing a plurality of hypotheses, where the hypotheses are arranged in at least a first and second disjoint group of hypotheses; and

    for storing questions for rejecting hypotheses of the second group;

    an output for supplying questions from the memory;

    an input for receiving initial data and answers to outputted questions;

    a processor programmed to;

    select questions from the stored questions for those hypotheses from the second group that are possible in dependence on the initial data;

    determine from at least one answer received in response to outputting the selected questions whether at least one of the hypotheses of the second group is possible; and

    in response to determining that no hypothesis of the second group is possible, supply via the output a most likely hypothesis of the first group in dependence on at least the initial data.
