Tessellations aren’t just eye-catching patterns—they can be used to crack complex mathematical problems. By repeatedly ...

Abstract: This paper focuses on a distributed nonsmooth composite optimization problem over a multiagent networked system, in which each agent is equipped with a local Lipschitz-differentiable ...

Abstract: We propose a new randomized Bregman (block) coordinate descent (RBCD) method for minimizing a composite problem, where the objective function could be either convex or nonconvex, and the ...

It was dark and silent, with a chill in the air, as an army of police vehicles blue-lighted their way through the city, headed for one destination. If you told me at 6.20am that Merseyside Police were ...
