Abstract: The adaptive computing system disclosed herein employs a data structure involving a multiplicity of classifiers, each of which includes a match string of characters which the system attempts to match up with messages generated either by the environment or by other classifiers. Associated with each match string is a response message definer or action part which defines the response to be given when a match is obtained. To facilitate matching in a noisy or changing environment, there is associated with each character in the match string a weighting value and the degree of match is judged by means of a score value which is a function of the weighting values of the characters which match between the match string and the message.
