quadratic convergence meaning in Chinese

二次收敛
二阶收敛性

Under appropriate conditions , we obtain the global and quadratic convergence of the proposed method
在适当的条件下，我们证明了算法的全局收敛性和二阶收敛性。
We have deduced the iterative formula by the theory of the dynamic system , proved that the quadratic convergence holds under the weak conditions , and done the numerical experiments
利用动力系统理论推导出该方法的迭代公式，证明其在某些弱条件下至少是二阶收敛的，最后给出了数值结果。
On the basis of this reformulation , it is proved that the system of nonsmooth equations is strongly semismooth so that the generalized newton method for solving this system possesses locally quadratic convergence
在此基础上，证明了非光滑方程是强半光滑的，因而解此方程的广义牛顿法具有局部二次收敛性。
It exploits the structured of the hessian matrix of the objective function sufficiently . an attractive property of the structured bfgs method is its local superlinear / quadratic convergence property for the nonzero / zero residual problems . the local convergence of the structured bfgs method has been well established
它们充分利用了目标函数的hesse矩阵的结构以提高算法的效率，该算法的显著优点是对于零残量问题具有二阶收敛性而对于非零残量问题具有超线性收敛性。
