Kolosnitsyn A. Simplex embedding method in decomposition of large sparse convex nondifferentiable optimization problems // CEUR Workshop Proceedings. Vol.2098. 2018. P.189-199. We consider an adaptation of the simplex embedding method to the decomposition of large-scale convex problem with sparse block-wise constraint matrix. According to the Lagrangean relaxation technique such problem is reduced to the maximization of nondifferentiable concave function with subgradient that can be easily calculated...

Modified simplex imbeddings method in convex non-differentiable optimization // CEUR Workshop Proceedings. Vol.1623. 2016. P.226-233. We consider a new interpretation of the modified simplex imbeddings method. The main construction of this method is a simplex which contains a solution of convex ...
