给出了求解无约束优化问题的一种共轭下降算法,该算法具有充分下降性的共轭梯度公式。在较为温和的条件下,利用宽松的非精确线搜索条件得到全局收敛性结果,同时数值实验表明了算法的有效性。
A conjugate descent method for unconstrained optimization was proposed. The method is of the sufficient descent property. Underan inexact line search condition and some other mild conditions, the global convergence was established. Preliminary numerical results show that the proposed method is promsing.
