Roger Fletcher is a mathematician known for his work in the fields of applied mathematics and numerical analysis, specifically in optimization and algorithms. He is particularly noted for his contributions to the development of iterative methods for solving linear and non-linear optimization problems. One of his notable achievements is the Fletcher-Reeves method, a popular algorithm for unconstrained optimization, which is part of the broader family of gradient descent methods.
