Patent ID: 8175998

Claim:
A method for valuating an object with a computer system, comprising the steps of: assigning start value in a range from 0 to 1 to a weight for a rule; determining a temporal progression of the weight in the range from 0 to 1 with an evolutionary algorithm; identifying convergence of the weight to a limit value; selecting the limit value of the weight as a new weight; determining a value of an object under the rule from features of the object; weighting the value of the object with the new weight to form a weighted value of the object; and valuating the object based on the weighted value of the object, wherein an expert system is implemented in a computer, includes a rule base and the rule is hierarchically combined with additional rules from the rule base, wherein numerical, categorial or fuzzy conclusions, or a combination thereof, of the additional rules are logically combined to form a premise of the rule.
