"WebFixed point 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). Then the fixed point equation is true at, and only at, a root of f. Fixed point iteration shows that evaluations of the function g can ... " - Fixed point convergence
