TRUSTS: Scheduling randomized patrols for fare inspection in transit systems using game theory
Zhengyu Yin,Albert Xin Jiang,Milind Tambe,Christopher Kiekintveld,Kevin Leyton-Brown,Tuomas Sandholm,John P. Sullivan +6 more
TL;DR: This paper presents TRUSTS, an application for scheduling randomized patrols for fare inspection in transit systems, an efficient algorithm for computing such patrol strategies and presents experimental results using real-world ridership data from the Los Angeles Metro Rail system.

TRUSTS: scheduling randomized patrols for fare inspection in transit systems
Zhengyu Yin,Albert Xin Jiang,Matthew P. Johnson,Milind Tambe,Christopher Kiekintveld,Kevin Leyton-Brown,Tuomas Sandholm,John P. Sullivan +7 more
TL;DR: TRUSTS as discussed by the authors models the problem of computing patrol strategies as a leader-follower Stackelberg game, where the objective is to deter fare evasion and hence maximize revenue.
Journal ArticleDOI
Game-theoretic security patrolling with dynamic execution uncertainty and a case study on a real transit system
Francesco Maria Delle Fave,Albert Xin Jiang,Zhengyu Yin,Chao Zhang,Milind Tambe,Sarit Kraus,John P. Sullivan +6 more
TL;DR: This paper presents a novel general Bayesian Stackelberg game model for security resource allocation in dynamic uncertain domains, and presents results from a real-world experiment on Metro trains in Los Angeles validating the MDP-based model, and most importantly, concretely measuring the benefits of SSGs forSecurity resource allocation.
From Drug Wars to Criminal Insurgency: Mexican Cartels, Criminal Enclaves and Criminal Insurgency in Mexico and Central America. Implications for Global Security
TL;DR: In this article, the authors examine the dynamics of transnational organized crime in Mexico and examine the exploitation of weak governance and areas (known as "lawless zones," "ungoverned spaces," "other governed spaces," or "zones of impunity") where state challengers have created parallel or dual sovereignty, or 'criminal enclaves' in a neo-feudal political arrangement.
Journal ArticleDOI
Drug Cartels, Street Gangs, and Warlords
TL;DR: The nature of crime and conflict has changed and continues to evolve as discussed by the authors, and the now and future war is and will be influenced by irregular combatants that utilize technology and net-computing.
