Fixed point convergence

When constructing a fixed-point iteration, it is very important to make sure it converges to the fixed point. We can usually use the Banach fixed-point theorem to show that the fixed point is attractive. Attractors. Attracting fixed points are a special case of a wider mathematical concept of attractors. See more In numerical analysis, fixed-point iteration is a method of computing fixed points of a function. More specifically, given a function $${\displaystyle f}$$ defined on the real numbers with … See more An attracting fixed point of a function f is a fixed point xfix of f such that for any value of x in the domain that is close enough to xfix, the fixed-point iteration sequence The natural cosine function ("natural" means in radians, not degrees or other units) has exactly … See more The term chaos game refers to a method of generating the fixed point of any iterated function system (IFS). Starting with any point x0, successive iterations are formed as xk+1 = fr(xk), where fr is a member of the given IFS randomly selected for each iteration.

The rootfinding problem f(x) = 0 can always be transformed into another form, g(x) = x, known as the fixed point problem. Given f, one such transformation is to define g(x) = x − f(x).
