Resilient multi-dimensional consensus in adversarial environment

چکیده
This paper considers the multi-dimensional consensus in networked systems, where some of agents might be misbehaving (or faulty). Despite influence these misbehaviors, benign aim to reach an agreement while avoiding being seriously influenced by faulty ones. To this end, first a general class algorithms, each agent computes “auxiliary point” based on received values and moves its state towards point. Concerning generic form, we present conditions for achieving resilient obtain lower bound exponential convergence rate. Assuming that number malicious is upper bounded, two specific algorithms are further developed obtained conditions. Particularly, solution, Helly’s Theorem, achieves within convex hull formed agents’ initial states, auxiliary point can efficiently computed through linear programming. On other hand, second algorithm serves as “built-in” security guarantee standard average sense performance coincides exactly with ones absence nodes also resisting serious adversarial environment. Some numerical examples provided end verify theoretical results.

Safe and Resilient Multi-vehicle Trajectory Planning Under Adversarial Intruder
Provably safe and scalable multi-vehicle trajectory planning is an important and urgent problem. Hamilton-Jacobi (HJ) reachability is an ideal tool for analyzing such safetycritical systems and has been successfully applied to several smallscale problems. However, a direct application of HJ reachability to multi-vehicle trajectory planning is often intractable due to the “curse of dimensionalit...
متن کاملLearning Consensus in Adversarial Environments
Due to the highly uncertain and dynamic nature of military conflict, enabling autonomous agents to gracefully adapt to mission and environmental changes is a very challenging task. These capabilities are necessary in the asymmetric battles waged against insurgencies, where enemy combatants quickly adapt to Army strategies and tactics. The United States Army, Air Force, and Navy have recently sh...
متن کاملClassifying Adversarial Behaviors in a Dynamic Inaccessible Multi-Agent Environment
Developing intelligent agents for multi-agent, inaccessible, adversarial environments is arguably one of the most challenging areas in artificial intelligence today. Great strides have been made in developing emergent cooperation among teammates, but less progress has been made in quickly and automatically changing overall team strategy in response to adversary actions. One way that humans do s...

متن کاملResilient Consensus for Infinitely Many Processes
We provide results for implementing resilient consensus for a (countably) infinite collection of processes. – For a known number of faults, we prove the following equivalence result: For every t ≥ 1, there is a t-resilient consensus object for infinitely many processes if and only if there is a t-resilient consensus object for t + 1 processes. – For an unknown or infinite number of faults, we c...
