Concave lenses are less common than convex lenses in optical engineering, but they still have some useful applications. Some examples of devices that use concave lenses are eyeglasses, peepholes ...

In this paper, we propose a first-order optimization method for solving saddle-point problems when the data is distributed over a strongly connected weight-balanced network of nodes. Our solution is ...

In this paper, we propose a sequential smoothing algorithm for solving large scale convex-concave saddle point problems. We prove that this class of algorithms achieves the convergence rate O(1/√ε) in ...

Difference between Concave vs Convex Lens: Isn’t physics one of those subjects that almost every student is scared of? Well why not, given the complexity of problems and difficulty level of the ...
