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 ...

WebDec 3, 2024 · Fixed point iteration is not always faster than bisection. Both methods generally observe linear convergence. The rates of convergence are $ f'(x) $ for fixed-point iteration and $1/2$ for bisection, assuming continuously differentiable functions in one dimension.. It's easy to construct examples where fixed-point iteration will converge … WebNov 19, 2024 · The convergence criteria of FP method states that if g' (x)<1 then that form of g (x) should be used. This will make sure that the slope of g (x) is less than the slope of straight line (which is equal to 1). If this condition does not fulfill, then the FP method may not converge. Convergence of fixed point method graphically.

WebNov 20, 2015 · For small x, we have sinx ≈ x − x3 / 6. So your fixed point iterations are approximately x0 = π 2, xk + 1 = xk − x3k 6. We may further approximate this discrete process by a differential equation x(0) = π 2, x ′ (t) = − x(t)3 6. This equation can be solved analytically, giving x(t) = 1 √1 3t + x(0) − 2, which is a function that ...
