Optimal Distributed Optimization on Slowly Time-Varying Graphs
Alexander Rogozin, César A. Uribe, Alexander Gasnikov +2
We study optimal distributed first-order optimization algorithms when the network (i.e., communication constraints between the agents) changes with time. This problem is motivated…
