Fixed-Point Iteration • For initial 0, generate sequence { }=0 ∞ by = ( −1). • If the sequence converges to , then =lim →∞ =lim →∞ ( −1)= lim →∞ −1 = ( ) A Fixed-Point Problem Determine the fixed points of the function =cos( ) for ∈−0.1,1.8 Convergence: The rate, or order, of convergence is how quickly a set of iterations will reach the fixed point. In contrary to the bisection method, which was not a fixed point method, and had order of convergence equal to one, fixed point methods will generally have a higher rate of convergence. If the derivative of the function at the fixed point zero, there will be linear convergence, which is the same as convergence of order one. If the derivative at the fixed point is equal to zero, it.

Fixed Point Iteration. Iteration is a fundamental principle in computer science. As the name suggests, it is a process that is repeated until an answer is achieved or stopped. In this section, we study the process of iteration using repeated substitution. More specifically, given a function g defined on the real numbers with real values and. method {del2, iteration}, optional Method of finding the fixed-point, defaults to del2, which uses Steffensen's Method with Aitken's Del^2 convergence acceleration [1] . The iteration method simply iterates the function until convergence is detected, without attempting to accelerate the convergence The fixed-point iteration method proceeds by rearranging the nonlinear system such that the equations have the form. where is a nonlinear function of the components . By assuming an initial guess, the new estimates can be obtained in a manner similar to either the Jacobi method or the Gauss-Seidel method described previously for linear systems. The point is located by moving left horizontally to the curve. These movements are equivalent to the first iteration in the fixed-point method: • Thus, in both the equation and in the plot, a starting value of is used to obtain an estimate of . The next iteration consists of moving to and then to . This iteration is equivalent to Figure 1 shows the convergence of the modified Ishikawa iteration, modified S-iteration, Thianwan new iteration, and proposed iteration to the common fixed point of and which is 1 in this numerical experiment, and it is clear that the proposed iteration process converges faster than others.. 5.

Fixed Point Iteration. It's an opened method for that reason requires an initial aproximation instead of an interval. In some cases doesn't converge in the root but when it does it's very fast. It begins with an equation f (x)=0 and the problem of finding the roots is replaced by other function x=g (x) from there is where the fixed points are. Acceleration methods are a group of methods that are often applied to iterative meth-ods, to improve the rate of convergence, given that the convergence of many iterative methods are slow. The Anderson acceleration method rst appeared in [1] in 1965. It has since been applied to electronic structure computations and appears in the survey paper.

In the literature there are several methods for comparing two convergent iterative processes for the same problem. In this note we have in view mostly the one introduced by Berinde in (Fixed Point Theory Appl. 2:97-105, 2004) because it seems to be very successful. In fact, if IP1 and IP2 are two iterative processes converging to the same element, then IP1 is faster than IP2 in the sense of. Fixed-point iteration is a method of computing fixed points of functions and there are several fixed-point theorems to guarantee the existence of fixed points.

As you say, the Newton's Method portion is working as intended. The problem is with your plotting portion. In your implementation, you generate 1 plot per iteration in your for loop.
