在Armijo型线搜索下共轭下降法的收敛性

摘要

我们提出了两种Armijo型线搜索,进而证明了这两种Armijo型线搜索可保证共轭下降法的下降搜索方向的充分下降性.并在这两种Armijo型线搜索下得到共轭下降法的收敛性结果.%We propose two Armijo-type line searches. Under the two Armijo-type line searches, convergence results are established for the CD method. The CD method can ensure all descent search directions satisfy the sufficient descent condition.
