Optimistic Distributed Submodular Coordination with Applications to Multi-Target Tracking with Multiple Robots
Pranjal Sharma, Atharva Navsalkar, Zirui Xu +1
We provide a distributed online algorithm for multi-agent submodular coordination in bandit environments, i.e., environments whose evolution is unknown a priori and may even adapt…
Asynchronous Distributed Bandit Submodular Maximization under Heterogeneous Communication Delays
Pranjal Sharma, Zirui Xu, Vasileios Tzoumas
We study asynchronous distributed decision-making for scalable multi-agent bandit submodular maximization. We are motivated by distributed information-gathering tasks in unknown en…
Distributed Equilibrium-Seeking in Target Coverage Games via Self-Configurable Networks under Limited Communication
Jayanth Bhargav, Zirui Xu, Vasileios Tzoumas +2
We study a target coverage problem in which a team of sensing agents, operating under limited communication, must collaboratively monitor targets that may be adaptively repositione…
Distributed Online Submodular Maximization under Communication Delays: A Simultaneous Decision-Making Approach
Zirui Xu, Vasileios Tzoumas
We provide a distributed online algorithm for multi-agent submodular maximization under communication delays. We are motivated by the future distributed information-gathering tasks…
Self-Configurable Mesh-Networks for Scalable Distributed Submodular Bandit Optimization
Zirui Xu, Vasileios Tzoumas
We study how to scale distributed bandit submodular coordination under realistic communication constraints in bandwidth, data rate, and connectivity. We are motivated by multi-agen…
Performance-Aware Self-Configurable Multi-Agent Networks: A Distributed Submodular Approach for Simultaneous Coordination and Network Design
Zirui Xu, Vasileios Tzoumas
We introduce the first, to our knowledge, rigorous approach that enables multi-agent networks to self-configure their communication topology to balance the trade-off between scalab…
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…
