Second, quasi-Newton methods are not applicable to all nonlinear optimization problems.

其次，拟牛顿法不能求解所有的非线性优化问题。

At the same time, the time taken to solve the system of normal equations for the least-square method is also reduced by using matrix updating techniques associated with Broydens quasi -Newton method.

同时运用拟牛顿矩阵校正技术解最小二乘方程组也减少了大量的计算时间。

As for the optimization problem, the damped Gauss-Newton Method algorithm is employed for obtaining its solution, and analysis the global convergence of the algorithm, also, the superlinear convergence rate and two order convergence rate of the algorithm is given.

对该优化问题，我们用阻尼高斯牛顿算法求解，并对算法的全局收敛性和超线性收敛速度进行了分析。

The Apple Newton, released in August 1993, was the first popular hand held personal digital assistant.

苹果公司于1993年8月发布了牛顿，它是第一台比较流行的手持式个人数字助手。

Based on the lumped mass method and Newton's second law, the numerical model of the force and movement response for fishing nets in current was set up, and then the dynamic deformation and the equilibrium configuration of the plane net in current along the positive direction of x-axis were studied by means of computer numerical simulation method.

基于集中质量点法和牛顿第二定律，建立了网衣在水流作用下的受力和运动响应数学模型。

Newton's law of motion as applied to the point mass is the well-known vector equation: F= ma .

牛顿运动定律应用于质点时就得到这样一个著名的向量方程式：F＝ma。
