摘要 本文给出 Luenberger(1973),Forrest 和 Tomlin(1972)提出的分解单纯形法的 ABS 表达形式.由 Huang 算法实现 QR 分解单纯形法.还用 ABS 算法构造出当基发生变化时 Givens 变换的校正公式. We present the ABS representations of the factorization simplex methods given by Luenberger (1973)and Forrest and Tomlin(1972).The QR decomposition simplex method is implemented by the Huang algorithm.The Givens transformations,needed when the basis is changed,are constructed via the ABS algorithm.
