Claim One:
1. A method of conducting multi-objective design optimization of a product using adaptive classification for selecting design alternatives comprising: (a) receiving a definition of a design space and an objective space for conducting multi-objective design optimization of a product in a computer system having a design optimization application module installed thereon, the design space being defined by a plurality of design variables while the objective space being defined by a plurality of design objectives; (b) initially selecting, by the design optimization application module, a first set of design alternatives within the design space; (c) determining, by the design optimization application module, whether each of the first set is a non-dominated design alternative by evaluating said each of the first set in the objective space, whereby the non-dominated design alternative does not improve all of the design objectives; (d) partitioning, by the design optimization application module, the design space into first and second regions using a multi-dimensional space division scheme, the first region being part of the design space containing all of the non-dominated design alternatives while the second region containing remaining of the design space; (e) selecting, by the design optimization application module, a second set of design alternatives within the first region according to a predetermined selection scheme; (f) determining, by the design optimization application module, whether each of the second sets and the previously-determined non-dominated design alternatives is non-dominated in the objective space; (g) repartitioning, by the design optimization application module, the design space into the first region and the second region using the multi-dimensional space division scheme with respect to the newly-determined non-dominated design alternatives; and (h) repeating (e)-(g) until an end condition of the multi-objective design optimization is reached.
