Firstly, we introduced the structural form intelligent optimization (SFIO) basic theory and the methodological framework including the alternative scheme intelligent producing and innovative, intelligent evaluation, intelligent optimization selection and decision-making, knowledge automatic access, intelligent means, laying a foundation for farther study the SFIO theories and methods. Secondly, we gave a more comprehensive overview of DM techniques in SFIO, the important research results and the latest research progress such as Apriori-based, Bayes-based, ID3-based, NN-based, GA-based, RS-based and fuzzy RS-based algorithm, and their characteristics. These methods can mine FO knowledge from a different perspective, and possess a better complementary. This paper gives more comprehensive overview of the data mining technology in the SFIO.
