چکیده

In this paper, decentralized feedback control strategies are derived for min-max time consensus tracking of multi-agent systems with bounded inputs that are communicating over directed graphs. Each agent is a linear time invariant system with distinct and rational eigenvalues. The graph contains a directed spanning tree rooted at an agent which generates the reference trajectory for the other agents. This spanning tree is locally identified and the tail agent of each edge tries to match its states with that of the head of the edge in min-max possible time. Using recent Gröbner basis based methods by the authors, these local min-max time problems are solved by deriving Nash equilibrium feedback strategies for time optimal pursuit-evasion games. The local min-max strategies lead to global consensus tracking in min-max time under some conditions.

Directed One - Trees †

We identify the class of directed one-trees and prove the so-called min-max theorem for them. As a consequence, we establish the equality of directed tree-width and a new measure, d-width, on this class of graphs. In addition, we prove a property of all directed one-trees and use this property to create an O(n) recognition algorithm and an O(n) algorithm for solving the Hamiltonian cycle proble...

A method for analyzing the problem of determining the maximum common fragments of temporal directed tree, that do not change with time

In this study two actual types of problems are considered and solved: 1) determining the maximum common connected fragment of the T-tree (T-directed tree) which does not change with time; 2) determining all maximum common connected fragments of the T-tree (T-directed tree) which do not change with time. The choice of the primary study of temporal directed trees and trees is justified by the wid...

Min - Max Heaps

,4 simple implementation of doubleended priority queues is presented. The proposed structure, called a min-max heap, can be built in linear time; in contrast to conventional heaps, it allows both FindMin and FindMax to be performed in constant time; Insert, DeleteMin, and DeleteMax operations can be performed in logarithmic time. Min-max heaps can be generalized to support other similar order-s...

Minimizing the Maximum End-to-End Network Delay: Hardness, Algorithm, and Performance

We study a flow problem where a source streams information to a sink over a directed graph G , (V,E) possibly using multiple paths to minimize the maximum end-to-end delay, denoted as Min-Max-Delay problem. Different from the maximum latency problem, our setting is unique in that communication over an edge incurs a constant delay within an associated capacity. We prove that Min-Max-Delay is wea...
