Wiki里是这样写的:牛顿法(Newton's method)是一种近似求解方程的方法,它使用函数f(x)的泰勒级数的前面几项来寻找方程f(x)=0的根。 它最初由艾萨克•牛顿在《流数法》(Method of Fluxions,1671年完成,在牛顿死后的1736年公开发表)。 按我的理解,起初牛顿法和最优化没什么关系(在那个年代应该还没有最优化这...
quasi-Newton methodOPTIMAL-DESIGNSTRUCTURAL OPTIMIZATIONSUBJECTWe consider optimal design problems in stationary diffusion for mixtures of two isotropic phases. The goal is to find an optimal distribution of the phases such that the energy functional is maximized. By following the identity perturbation ...

We survey the history of the method, its main ideas, convergence results, modifications, its global behavior. We focus on applications of the method for various classes of optimization problems, such as unconstrained minimization, equality constrained problems, convex programming and interior point ...
In calculus, Newton’s method is an iterative method for finding the roots of a differentiable function F , which are solutions to the equation F(x)=0 . In optimization, Newton's method is applied to the derivative f′ of a twice-differentiable function f to find the roots of the deriva...
