属性约简是粗糙集的核心问题之一。本文基于决策规则给出属性约简相关结论和属性重要性,提出启发式约简算法,引入黄金分割法思想,提高算法效率,并以实例验证算法有效性和正确性。
屬性約簡是粗糙集的覈心問題之一。本文基于決策規則給齣屬性約簡相關結論和屬性重要性,提齣啟髮式約簡算法,引入黃金分割法思想,提高算法效率,併以實例驗證算法有效性和正確性。

Attribute reduction is one of the key problems of rough set.In this paper,some relative conclusions of attribute reduction and definition of attribute significance were proposed based on decision rule.This paper also gives heuristic algorithm,which used golden-section thinking to improve algorithm efficiency.The algorithm efficiency and correctness have been illustrated with an example.
