If the function is concave,then the Newton Raphson method is gauranteed to converge to the correct answer. If the functionis convex for some values of x, then the algorithm may or may not converge. The NR algorithm mayconverge to a local maximum and not the global maximum, it might ...
Lemma 2 Newton-Raphson method 牛顿-拉弗森方法,或者叫牛顿迭代法,是一种利用了收敛性迭代求方程近似解的有效方法,具体原理网上有很多,我们这里只使用它的迭代形式: x_{n+1}=x_n-\frac{f(x_n)}{f'(x_n)} Lemma 3 Hensel Lemma 若我们已知f(x)在模p^{k-1}(k\geq 2)意义下的一个解f(r)\equi...
Newton's square-root method References in periodicals archive ? Then the likelihood function of the model is derived, from which unknown parameters can be estimated via Newton-Raphson algorithm or Markov Chain Monte Carlo (MCMC) technique in Section 3. By the Newton-Raphson algorithm [13], it ...
In numerical analysis, Newton's method (also known as the Newton–Raphson method), named after Isaac Newton and Joseph Raphson, is a method for finding successively better approximations to the roots (or zeroes) of a real-valued function. It is one example of a root-finding algorithm. ...
牛顿法(Newton’s method)又称为牛顿-拉弗森法(Newton-Raphson method),是一种近似求解实数方程式的方法。(注:Joseph Raphson在1690年出版的《一般方程分析》中提出了后来被称为“牛顿-拉弗森法”的数学方法,牛顿于1671年写成的著作《流数法》中亦包括了这个方法,但该书在1736年才出版。) ...

牛顿迭代法(Newton’smethod)又称为牛顿-拉夫逊(拉弗森)方法(Newton-Raphsonmethod),它是牛顿在17世纪提出的一种在实数域和复数域上近似求解方程的方法。 我想你可能只看得懂这个是牛顿提出的吧,其实它是牛顿解复杂方程的方法,通常这类方程没有求根公式,不像一元二次方程有...
Newton-Raphson算法 1. In this paper,a modified Newton-Raphson algorithm based on the Marquardt method is presented. 该方法用迭代法获得电磁波流动图像重建不适定逆问题稳定解,仿真结果表明该方法与修正的Newton-Raphson算法相比能快速而较高精度地重建出两相流断层图像。 2. Finally,Newton-Raphson algorithm ...
