1. A method of generating responses to a source of an input signal comprising a succession of messages, said source providing a reinforcement signal for good responses, said method comprising:

  • initially generating a population of classifiers, each classifier comprising;

    a match string;

    for each character in the match string, a weighting value;

    a response message definer; and

    a strength value for the classifier;

    for successive input signal messages performing the steps of;

    comparing the match string of each classifier to each successive input signal message provided by the source and generating a corresponding score value which is a function of the weighting values of the matching characters;

    comparing the score values generated by the different classifiers;

    outputting respective response messages for classifiers selected stochastically on a basis favoring those classifiers having the better scores; and

    modifying, as a function of a received reinforcement signal, the strength values for classifiers whose response messages were appropriate.
