Pursuit-evasion with fixed beams
2016 IEEE International Conference on Robotics and Automation (ICRA), 2016We introduce a complete algorithm for solving a pursuit-evasion problem in a simply-connected two-dimensional environment, for the case of a single pursuer equipped with fixed beam sensors. The input for our algorithm is an environment and a collection of sensor directions, in which each is capable of line-of-sight detection in a fixed direction.

Pursuit-evasion using beam detection
Proceedings 2000 ICRA. Millennium Conference. IEEE International Conference on Robotics and Automation. Symposia Proceedings (Cat. No.00CH37065), 2002We present an algorithm for searching a 2D environment for unpredictable moving targets using only beam-based detection. One or more pursuers move along the environment boundary, and carry a rotating beam that detects evaders. The beam could correspond in practice to a laser or a camera.

On Porter's pursuit-evasion games
Journal of Optimization Theory and Applications, 1970A minimax problem for Porter's class of functionals is considered in the case when the two players' strategies are elements of convex and strongly or weakly compact subsets of real Hilbert spaces. Functional analysis is used to prove sufficient conditions ensuring the existence of saddle points.

On Function Space Pursuit-Evasion Games
SIAM Journal on Control, 1967Functional analysis is used to analyze a minimax problem for a class of functionals on a Hilbert space. The abstract solution is then interpreted, through examples, in the context of pursuit-evasion games. The examples given are chosen to emphasize the breadth of the analysis. Some computational aspects of the minimax problem are considered.

Stochastic Linear Pursuit-Evasion Game
2012The 1950’s saw the introduction of guided interceptor missiles and the launching of Sputnik I. Questions on pursuit and evasion were suddenly in everyone’s mind. What is the best strategy to intercept a moving target? How can friendly planes best avert midair collisions?

Stochastic multi‐player pursuit–evasion differential games
International Journal of Robust and Nonlinear Control, 2007AbstractAutonomous aerial vehicles play an important role in military applications such as in search, surveillance and reconnaissance. Multi‐player stochastic pursuit–evasion (PE) differential game is a natural model for such operations involving intelligent moving targets with uncertainties.

Visibility-Based Pursuit-Evasion with Bounded Speed
The International Journal of Robotics Research, 2008In this paper we present a study on the visibility-based pursuit— evasion problem in which bounds on the speeds of the pursuer and evader are given. In this setting, the pursuer tries to find the evader inside a simply connected polygonal environment, and the evader in turn tries to avoid detection.

Noisy satellite pursuit-evasion guidance
Journal of Guidance, Control, and Dynamics, 1989Guidance laws are developed for both pursuer and evader satellites, using a simplified dynamic model of the one-on-one satellite encounter. Dynamic symmetry is assumed: both have noisy azimuth-elevation data, the criterion for each is the expected miss, and both satellites have on-off thrust inputs of controllable direction.

Vision-Based Pursuit-Evasion in a Grid
SIAM Journal on Discrete Mathematics, 2008We revisit the problem of pursuit-evasion in a grid introduced by Sugihara and Suzuki [SIAM J. Discrete Math., 2 (1989), pp. 126-143] in the line-of-sight vision model. Consider an arbitrary evader Z with the maximum speed of 1 who moves (in a continuous way) on the streets and avenues of an n × n grid Gn.
