SUMMARY:Cooperative Strategies and Capture Zones in Multi-Player Pursuit-Ev
 asion Games
DESCRIPTION:Lecturer:Shmuel Hayoun\n Faculty:Department of Aerospace Engine
 ering\n Institute:Technion – Israel Institute of Technology\n Location:C
 lassroom 165\, ground floor\, Library\, Aerospace Eng.\n Zoom: \n Abstract
 : \n Details: \n Cooperative strategies are becoming more and more popular
  with the continuing evolution and advancement in decision making capabili
 ties of autonomous vehicles. Utilizing multiple agents to perform a given 
 task can be beneficial even in cases when the goal is achievable by a sing
 le agent. With regard to interception engagements of an intelligent target
 \, through shared information and coordinated actions the capability requi
 rements and/or the number of required agents in order to capture the targe
 t may be relaxed and reduced\, respectively. It is therefore a great point
  of interest\, when analyzing such problems\, to discern under what condit
 ions the evader's capture can be guaranteed (and whether or not these cond
 itions are dependent on the number of pursuers and their capabilities) and
  which element of cooperation (if any) can help to achieve this guarantee.
 \nWe will begin the talk with an examination of the solution of a linear 1
 -on-1 interception engagement with multiple bounded control inputs\, formu
 lated as a two-person\, zero-sum\, pursuit-evasion game\, from which we de
 rive the conditions under which a single pursuer may guarantee the exact c
 apture of a single (possibly) evading target\, extending current known res
 ults. This will be followed by an analysis of a 2-on-1 pursuit-evasion gam
 e (a team of two pursuers vs. a single evader) in which we consider two di
 fferent formulations: the first including a product-form cost function and
  the second using a guaranteed miss approach. Based on the latter\, we wil
 l propose a cooperative pursuit strategy for a couple of “weak” pursue
 rs and illustrate its performance through simulations. Finally\, following
  some observations from the 2-on-1 game\, we will present necessary and su
 fficient conditions by which a group of (possibly) cooperating pursuers ma
 y guarantee point capture of a single (possibly) evading target in a gener
 al n-on-1 linear engagement\, showing that\, with respect to guaranteeing 
 point capture\, the pursuers cannot actually benefit from cooperating with
  one another.
