Pursuit-evasion games in mobile networks
… in this area, we model the intrusion as a pursuit-evasion game in continuous time and space. We model the intruder as an antagonistic agent and apply tools from differential game theory in order to obtain the optimal motion strategies for the agents to track the intruder as well as evade …

Multi-agent Coordination Algorithms for Pursuit-Evasion
… intelligence is a paramount concern. Based on pursuit-evasion games, this thesis investigates the safe distributed implicit coordination of large-scale multi-agent systems, as some self-organizing systems in nature. Particularly, five research questions are answered in the thesis: (1) how to …

Visibility-Based Pursuit-Evasion with Probabilistic Evader Models
<p>We propose an algorithm for a visibility-based pursuit-evasion problem in a simply-connected two-dimensional environment, in which a single pursuer has access to a probabilistic model describing how the evaders are likely to move in the environment. The application of our algorithm can be best …

Learning in the Multi-Robot Pursuit Evasion Game
… robots playing the differential forms of the pursuit-evasion (PE) game by proposing different learning algorithms. The intended learning algorithms are used to reduce (1) the computational requirements as much as possible, without affecting the overall performance of the learning algorithm, …

Optimal pursuit/evasion spacecraft trajectories in the hill reference frame
The pursuit/evasion game for two spacecraft is significantly simplified by being described with a linearized system of equations of motion. A pursuit/evasion game is also known as a “minimax” problem, because the objective of the pursuer is to minimize the time to capture, while the evader's goal …

Pursuit-evasion and time-dependent gradient flow in singular spaces
… we consider an applied problem, namely, pursuit-evasion games. These problems are related to robotics, control theory and computer simulations. We want to find the solution curves of differential equations for pursuit-evasion games, and investigate the properties of solution curves. …

A tensor-train-decomposition-based algorithm for high-dimensional pursuit-evasion games
… feedback strategies for high-dimensional pursuit-evasion games. When a problem is high-dimensional or involves a state space that is defined by several variables, various methods used to solve pursuit-evasion games often require unrealistic computation time. This problem, called the curse …

A State Space Partitioning Scheme for Vehicle Control in Pursuit-Evasion Scenarios
Pursuit-evasion games are the subject of a variety of research initiatives seeking to provide some level of autonomy to mobile, robotic vehicles with on-board controllers. Applications of these controllers include defense topics such as unmanned aerial vehicle (UAV) and unmanned underwater vehicle …

Optimal Control for a Two Player Dynamic Pursuit Evasion Game; The Herding Problem
In this dissertation we introduce a new class of pursuit-evasion games; the herding problem. Unlike regular pursuit evasion games where the pursuer aims to hunt the evader the objective of the pursuer in this game is to drive the evader to a certain location on the x-y grid. The dissertation deals …

Using Multiplayer Differential Game Theory to Derive Efficient Pursuit-Evasion Strategies for Unmanned Aerial Vehicles
… less computationally demanding differential pursuit-evasion game-based algorithms are presented. The purpose of the algorithms is to quickly derive interception strategies for a team of autonomous vehicles. The algorithms are applicable to scenarios with different base assumptions, that is, …

Optimal control problems, curves of pursuit
We study a class of problems known as pursuit-evasion problems (PE). These problems can be understood as special cases of optimal control problems. After describing the two main principles to study optimal control problems, namely Pontryagin's maximum principle and Bellman's method of dynamic …

Variations on Zombies and Survivor in Simple Polygons
We study the pursuit-evasion game of a zombie and a survivor on point visibility graphs of simple polygons. A zombie has one objective: catch a survivor by occupying the vertex occupied by the survivor. On its turn, a zombie can only move on the first edge of a \textit{geodesic} path to the …
