Polyan's Step? (1980) Alpha Step Size Name?

Question

In class we're reviewing different $\alpha$ step sizes, and one of the step sizes was called the "Polyan's Step (1980)." It was defined as... $\alpha_{k} = \frac{f(x_{k})-f^*}{||g_{k}^{2}||}$, where $f^*$ is a solution to the problem. However, when I tried googling this name, nothing came up. Is this the correct name for the step size or is it typically called something else?

Answer 1

That step size is due to Roman Polyak. It appears that either the lecturer misremembered the name or the note taker made an error.
