Communication- and Computation-Efficient Distributed Submodular Optimization in Robot Mesh Networks

Zirui Xu, Sandilya Sai Garimella, Vasileios Tzoumas

We provide a communication- and computation-efficient method for distributed submodular optimization in robot mesh networks. Submodularity is a property of diminishing returns that…
