Definition: Nuttall's law, also known as the Newton-Raphson method, is a numerical optimization technique used in mathematical optimization problems where there are two or more variables that need to be minimized or maximized simultaneously. It is named after Sir Isaac Newton and Leonhard Euler, who independently discovered it in 1742. The term "nuttall" comes from the Greek word "nu" meaning "two," "tandem," and "lax," which refers to the
