Lagrangian dual reformulation
Tīmeklis2024. gada 3. sept. · For nonconvex optimization problems, possibly having mixed-integer variables, a convergent primal-dual solution algorithm is proposed. The approach applies a proximal bundle method to certain augmented Lagrangian dual that arises in the context of the so-called generalized augmented Lagrangians. We … http://www.ai.mit.edu/projects/jmlr/papers/volume1/mangasarian01a/mangasarian01a.pdf
