May 17, 2023 · Bibliographic details on A Quasi-Newton Primal-Dual Algorithm with Line Search.
The paper proposes a linesearch for a primal-dual method. Each iteration of the linesearch requires an update of only the dual (or primal) variable.
Backtracking line-search is an old yet powerful strategy for finding better step size to be used in proximal gradient algorithms.
In this paper, we propose a line-search-based primal-dual interior-point algorithm of the “feasible” variety for which global and fast local convergence are ...
