| Abstract: | In the article, the authors have deduced the equivalence express forms. They have designed the algorithm program that can calculate the significance of condition attribute subsets from the supplementary sets of decision-making algorithm positive sets. The authors have also designed the algorithm program that can calculate the support degree of condition attribute subsets from the decision-making algorithm positive sets. In the end, they have used them analyzing the factors of identified rock species in the geology. The result shows the algorithm program designed in the article is effective and feasible. |
