WebMay 28, 2024 · In this paper, we have developed a gradient-based algorithm for multilevel optimization with levels based on their idea and proved that our reformulation asymptotically converges to the original multilevel problem. As far as we know, this is one of the first algorithms with some theoretical guarantee for multilevel optimization.
