Kiefer-wolfowitz algorithm
WebBy adding stochastic dithers to local objective functions and constructing randomized differences motivated by the Kiefer--Wolfowitz algorithm, we propose a distributed … The Kiefer–Wolfowitz algorithm was introduced in 1952 by Jacob Wolfowitz and Jack Kiefer, and was motivated by the publication of the Robbins–Monro algorithm. However, the algorithm was presented as a method which would stochastically estimate the maximum of a function. Let be a function which has a maximum at the point . It is assumed that is unknown; however, certain observations , where , can be made at any point . The structure of the algorithm follows a gradien…

An important part of our criterion is an additional vector of experimental conditions, which may affect the design.
