精确线搜索下一种新的混合共轭梯度法
A NEW CLASS OF MIXED CONJUGATE GRADIENT METHOD WITH EXACT LINE SEARCH

本文对于大规模无约束优化问题提出了一种新的混合βκ公式，从而提出了一种具有充分下降性的混合共轭梯度法.利用精确线搜索步长规则，在适当的假设下证明了新算法的全局收敛性.
In this paper, a new mixed iterative formula of coefficient βκ is proposed for large-scale unconstrained optimization problems, and a mixed conjugate gradient method with sufficient descent is proposed. By using the exact line search step rules, we prove the global convergence of the new algorithm under the appropriate assumptions
