Polyak-Type Extragradient Methods for Monotone Root-Finding Problems
TaeHo Yoon, Sayantan Choudhury, Ezra Greenberg +1
We study Polyak-type step-size selection for extragradient methods for solving deterministic and stochastic monotone root-finding problems. We show that the known projection-type c…
