摘要:
本文设计了一个新的参数公式,在适当条件下,建立在此参数公式上的共轭梯度算法在WWP线搜索下全局收敛。初步的数值实验结果表明新算法是有效的。
This paper has designed a new parameter formula. The conjugate gradient algorithm which based on the parameter formula is global convergence with WWP line search under appropriate condi-tions. Preliminary numerical results turn out that this new method is effective.
