WebTrust region approach involves constructing a model function m k that approximates the function f in the region, Δ, near the current point x k . The model m k is often a quadratic obtained by a Taylor Series expansion of the function around x k. m k ( p) = f + ∇ f ( x k) T p + 1 2 p T B k p. where B k is an approximation of the Hessian.
