在粗糙集理论中属性约简是个NP—hard问题，已有的方法都有不同的局限性．由蚁群算法的启发，通过粗糙集将条件属性集映射到有向图结构，并采用蚁群协作共同完成求解，提出了属性约简的蚁群算法．%Attribute reduction in rough sets theory is a kind of NP - hard problem. The existing methods for solving this problem have limits. By the construction of the graph expressing the combination of condition sets, a new approach to attribute reduction based
