Newton's method in optimization - Wikipedia
https://en.wikipedia.org/wiki/Newton's_method_in_optimizationThe central problem of optimization is minimization of functions. Let us first consider the case of univariate functions, i.e., functions of a single real variable. We will later consider the more general and more practically useful multivariate case. Given a twice differentiable function , we seek to solve the optimization problem Newton's method attempts to solve this problem by constructing a sequence from an initial gues…
Newton's method - Wikipedia
https://en.wikipedia.org/wiki/Newton's_methodWhen dealing with complex functions, Newton's method can be directly applied to find their zeroes. Each zero has a basin of attraction in the complex plane, the set of all starting values that cause the method to converge to that particular zero. These sets can be mapped as in the image shown. For many complex functions, the boundaries of the basins of attraction are fractals.
Newton's Method -- from Wolfram MathWorld
https://mathworld.wolfram.com/NewtonsMethod.htmlNewton's method, also called the Newton-Raphson method, is a root-finding algorithm that uses the first few terms of the Taylor series of a function f(x) in the vicinity of a suspected root. Newton's method is sometimes also known as Newton's iteration, although in this work the latter term is reserved to the application of Newton's method for computing square roots.
