1. In robust design problems using a search engine, a method of selecting one of a first and second semiconductor technology design candidates, the method comprising: randomly sampling said first semiconductor technology design candidate to obtain a first random sample; determining at least one objective function value from said first random sample; randomly sampling said second semiconductor technology design candidate to obtain a second random sample; determining at least one objective function value from said second random sample; determining, based on said first and second objective function values comparison-oriented statistical estimates relating the first and second semiconductor technology design candidates; selecting, if possible, based on at least one decision rule and said comparison-oriented statistical estimates, one of said semiconductor technology design candidates; and repeating the previous steps until one of said semiconductor technology design candidates has been selected.
