Indeed, the application at LAX uses a Bayesian Stackelberg game. In this letter, an antijamming Bayesian Stackelberg game with incomplete information is proposed INTRODUCTION In the algorithmic game theory community, and especially the multiagent systems part of … games or Bayesian games, the computational problem becomes hard again [5].

Each follower type is ing Bayesian Stackelberg game model, there is only one leader type (e.g., only one police force), although there can be multiple follower types (e.g., multiple attacker types trying to inﬁltrate se-curity) [30].

Bayesian Stackelberg game. We modify the Bayesian Stackelberg game into a Bayesian zero-sum game by exploiting our problem’s struc-ture, allowing us to use a much more efﬁcient minimax LP.

EL L R ER U 9,10 Bayesian Stackelberg Game: In a Bayesian game of N agents, each agent nmust be one of a given set of types. We assume that there is only one Game theory, Bayesian Stackelberg games, robustness, security, uncertainty, risk analysis 1. Our main contributions are: 1) An e ective way to model MTD as BSG, 2) Show-case how the modeling leads to nding better MTD policies, 3) A methodology to nd most critical vulnerabilities (Note that there are symmetric solutions on the other side of the game where the row player puts most of the probability on D and the column player responds with ER.) Bayesian Stackelberg games address the challenges posed by our domain, they are at the heart of generating meaning-fullyrandomized schedules. tribution of our paper is mapping the problem of security schedul-ing as a Bayesian Stackelberg game [4] and solving it via the fastest optimal algorithm for such games, addressing the ﬁrst two chal-lenges. ing as a Bayesian Stackelberg game [4] and solving it via the fastest optimal algorithm for such games, addressing the ﬁrst two chal-lenges. A security game is a Stackelberg game played between a defender (the leader) and an attacker (the follower). The problem of nding an optimal policy for the leader to commit to in a Bayesian Stackelberg game is known to be NP-hard [6]. In this section, we first introduce the motivation to research active deception defense with a Bayesian Stackelberg game in Section 2.1. A Bayesian Stackelberg game is an incomplete information Stackelberg game in which each player must be one of a given set of types. Concretely, we consider a security agency who wants to protect two conservation areas, i.e., areas 1 and 2, from a poacher’s attack.’s attack. Each follower type is ing Bayesian Stackelberg game model, there is only one leader type (e.g., only one police force), although there can be multiple follower types (e.g., multiple attacker types trying to inﬁltrate se-curity)[30]. Bayesian Stackelberg Game Stackelberg Game + Leader’s uncertainty about the types of adversary he may face Introduction, Playing Games for Security Introduction Introduction, Playing Games for Security Example of 2. However, in many practical scenarios, the attacker and defender interact periodically, thus reducing the applicability of such models. Bayesian Stackelberg games allow us to explicitly model players as types, where each type can have its own preferences. Indeed, casting the problem as a Bayesian Stackelberg game, we have developed new algorithms that … Of course, problem structure has also been exploited (In a Bayesian game, some of the players have private information that is relevant to the payoffs; their private in-formation is encoded by their type.) Types lead to di erent sets of actions and payo tables. Subsequently, the Stackelberg active deception game is defined in Section 2.2. longer the fastest Bayesian Stackelberg game solution algorithm, and HB GS-F provides scale-up by an order of magnitude .
