A bilevel optiization based algorithm for solving a class of price equilibrium problems
Nguyen Ngoc Hai, Le Dung Muu, Nguyen Van Quy
We consider class of equilibrium models including the implicit Walras supply-demand and competitive models. Such a model in this class, in general, is ill-posed. We formulate such…

Adaptive multi-gradient methods for quasiconvex vector optimization and applications to multi-task learning
Nguyen Anh Minh, Le Dung Muu, Tran Ngoc Thang
We present an adaptive step-size method, which does not include line-search techniques, for solving a wide class of nonconvex multiobjective programming problems on an unbounded co…
