www.math-cs.gordon.eduFixed-Point Iterations Many root- nding methods are xed-point iterations. These iterations have this name because the desired root ris a xed-point of a function g(x), i.e., g(r) !r. To be useful for nding roots, a xed-point iteration should have the property that, for xin some neighborhood of r, g(x) is closer to rthan xis. This leads to the ...
UNCONSTRAINED MULTIVARIABLE OPTIMIZATION
www.ou.eduAt point 1, f(x) is greater than f at points .2 or 3. fixed for a given size simplex. Let us use a function of two variables to illustrate the procedure. At each iteration, to minimize f(x), f(x) is evaluated at each of three vertices of the triangle. The direction of search is oriented away from the point with the high-

Newton’s Method on a System of Nonlinear Equations
www.cmu.edu2.2 Attracting Fixed Points and Basins of Attraction We make the following useful observation: Observation The roots of a polynomial f are precisely the fixed points of Nf. Proof. Suppose ↵ is a fixed point of N.ThenN(↵)=↵ f(↵) f0(↵) = ↵ only if f(↵) = 0. In the other direction, suppose ↵ is a root of f of multiplicity m.Then
