Derivative free algorithm[edit]

It is written that this is a derivative free algorithm, but it actually uses the normal gradient descent (that is, derivatives) except on one variable at a time instead of considering the full gradient. Am I misunderstanding something or it's not true that this is a derivative free algorithm? — Preceding unsigned comment added by 84.226.196.209 (talk) 20:33, 28 February 2017 (UTC)[reply]
