Pick your Neighbor: Local Gauss-Southwell Rule for Fast Asynchronous Decentralized Optimization

1 code implementation15 Jul 2022 Marina Costantini, Nikolaos Liakopoulos, Panayotis Mertikopoulos, Thrasyvoulos Spyropoulos

In decentralized optimization environments, each agent $i$ in a network of $n$ nodes has its own private function $f_i$, and nodes communicate with their neighbors to cooperatively minimize the aggregate objective $\sum_{i=1}^n f_i$.

Problem-Adapted Artificial Intelligence for Online Network Optimization
