A Matheuristic for Leader-Follower Games Involving Facility Location-Protection-Interdiction Decisions [chapter]

Deniz Aksen, Necati Aras
2013 Studies in Computational Intelligence  
The players of the game are a system planner (the leader) and an attacker (the follower).  ...  Stackelberg games can be formulated as a bilevel programming problem where the upper and the lower level problems with conflicting objectives belong to the leader and the follower, respectively.  ...  For future research we suggest several extensions of this SND for which TSH can still prove an effective method to solve the upper level problem. The remainder of the chapter is organized as follows.  ...
