Offline Nash Solvers Meet Online Tree Search in Multi-Agent Games on Graphs
Mukesh Kumar, Yue Guan, Panagiotis Tsiotras
Computing Nash equilibrium policies in multi-agent Pursuit-Evasion games (PEG) is challenging due to the exponential growth of the joint state and action spaces with the number of…
Multi-Contact Force Estimation for Continuum Robots via Gaussian-Parameterized Factor Graphs
Aditya Prakash, Panagiotis Tsiotras
Continuum robots offer key advantages in navigating unstructured environments, but their safe operation requires accurate estimation of the external contact forces acting anywhere…
Performance-Driven Environment Abstraction with Multi-Timescale Learning
Yue Guan, Dipankar Maity, Panagiotis Tsiotras
We study performance-driven environment abstraction for decision-making in large Markov decision processes. Rather than preserving geometric or topological structure, we seek abstr…
Collaborative Navigation and Exploration with -Sparse Gaussian Processes
Evangelos Psomiadis, Dipankar Maity, Panagiotis Tsiotras
Collaborative navigation of heterogeneous robots in unknown environments poses significant challenges due to sensing, communication, and computational limitations. In this work, a…
Distributed Event-Triggered Distance-Based Formation Control for Multi-Agent Systems
Evangelos Psomiadis, Panagiotis Tsiotras
This paper addresses the problem of collaborative formation control for multi-agent systems with limited resources. We consider a team of robots tasked with achieving a desired for…
Strategic Concealment of Environment Representations in Competitive Games
Yue Guan, Dipankar Maity, Panagiotis Tsiotras
This paper investigates the strategic concealment of environment representations used by players in competitive games. We consider a defense scenario in which one player (the Defen…
