摘要
本文在关于归并依赖集的二元组集合闭包的求解算法的基础上给出了对称左部集的概念，同时讨论并给出了求全部对称左部集的多项式时间算法。
In this paper,the concept of symmetric left side set is given based on the document—The Algorithm to Find Duality Closed Collect of Merge Dependency Set D, the a polynomial-time algorithm to find all symmetic left side set is given.
