Abstract Meshfree methods are becoming an increasingly popular alternative to mesh-based of numerical simulation. The biggest stated advantage meshfree is the avoidance generating a mesh on computational domain. However, even today surprisingly large amount literature ironically uses nodes as point set that discretizes On other hand, already existing efficient generate clouds apparently not ver...

We consider composite minimax optimization problems where the goal is to find a saddle-point of large sum non-bilinear objective functions augmented by simple regularizers for primal and dual variables. For such problems, under average-smoothness assumption, we propose accelerated stochastic variance-reduced algorithms with optimal up logarithmic factors complexity bounds. In particular, strong...
