Nonlinear Root Finding and a Glimpse at Optimization
... The simplest root-finding method is the bisection method, which basically just performs a simple binary search. We begin by bracketing the root: this means finding two points x1 and x2 at which f (x) has different signs, so that we are guaranteed2 to have a root between x1 and x2 . Then we bisect th ...

A Bundle Method to Solve Multivalued Variational Inequalities
... p and we show how to build suitable approximations by means of a bundle strategy. In a second part, we prove the convergence of the general algorithm. We give conditions to ensure the boundedness of the sequence generated by the algorithm. Then we study the properties that a gap function must satisf ...

... • Theorem (Newton's Method Convergence) If f(x) has f’(x) and f’’(x) continuous, and r is a simple root of f(x), then there is some D such that if |x0 – r| < D then Newton’s method will converge quadratically to r. • Proof: It can be shown (using Taylor Series) that ...
