I particularly points out that this descending dimension Lagrange multiplier algorithm improves penalty function algorithm and advance accuracy to a certain degree.

特别要指出的是，该算法改进了罚函数法，并在一定程度上比罚函数法更精确。

Matrix used as encoding of the algorithm, and a penalty function is adopted to satisfy the multi-constraint.

该算法采用矩阵编码方案，建立罚函数满足课表问题中的多重约束条件。

This algorithm may be regarded as a variant of exterior point penalty function methods.

该算法可看作是外点罚函数法的一个变体。
