WitrynaNewton's method. Newton's method, also known as Newton-Raphson's method, is a very famous and widely used method for solving nonlinear algebraic equations.Compared to the other methods we will consider, it is generally the fastest one (usually by far). It does not guarantee that an existing solution will be found, however. WitrynaAimed to the nonlinear equations-finding problem that only one solution is found with the Newton and quasi-Newton methods and sometime no solution is found when the iteration diverges, combining Newton-downhill method with hyper-chaotic system, hyper-chaotic Newton-downhill method based on utilizing hyper-chaotic discrete …
