Generating set search
We call this method (simplex) gradient-informed generating set search, or GIGS for short. While the use of simplex gradients for directly determining the search pattern is novel to the best of our knowledge, previous works have explored applications of the concept in the DFO context. See more Loosely speaking, a first requirement is to assure that the feasible descent directions do not get ‘arbitrarily orthogonal’ to the search directions that … See more First of all, let us install some notational simplifications.
