摘要：
An algorithm of logical operations based on binary codes is applied in the calculation of the minimal hitting sets, which maps the minimal hitting sets problem to the 0/1 integer programming problem. The system is modeled and simulated to find out the minimal conflict sets and its entire candidate hitting sets are computed and confirmed by the bottom-up search algorithm, which defines each system element with binary codes and operates logical or". The comparison of the minimal conflict sets number and the contained elements number among different algorithms shows that the proposed algorithm is hardly affected. The calculation results of minimal conflict sets by different algorithms for an actual distribution network demonstrate the superiority of the proposed algorithm."
