NEW YORK – The Park Slope Food Co-op is more than a discounted indie grocer – though, on any given day, there are about 10 varieties of locally grown mushrooms and shoppers can buy a dozen ...

In this article, we introduce a convex combination-based distributed momentum method (CDM) for solving distributed optimization to minimize a sum of smooth and strongly convex local objective ...

Convex optimization with sparsity-promoting convex regularization is a standard approach for estimating sparse signals in noise. In order to promote sparsity more strongly than convex regularization, ...
