It should print 2. a sequential game where there is a leader (the Spammer here ) and a follower (the Defender D).. Stackelberg games are usually used to model strategic interactions between rational agents in markets on which there is some hierarchical competition. The principal difierence between the Cournot model and the Stack-elberg model is that instead of moving simultaneously (as in the Cournot model) the flrms now move sequentially. The follower, on the other hand, makes its decision assuming the leader 1220 We will talk about collusion, we will talk about Cournot, we will talk about Stackelberg games, and we will also talk about Bertrand games. To see the advantage of being a leader in Stackelberg game, consider the game between the leader and follower type 1 as shown in Figure 1 (left).

The stackelberg leader is playing a game with 2 players,and yet it produces the same as though it were a game with 1 player. Previous work has failed to resolve the defender’s dilemma of which strategy to select when the Consequently, it is essential to employ a game-theoretic modeling approach instead of a centralized approach for decentralized supply chain optimization. In Stackelberg game, the model owner is the buyer as it buys the learning service provided by the mobile devices. Although the numerical techniques should be those indicated in the Programme Structure, the economic topics may be adapted to the interest of the audience, and the aim is to have economic examples also when presenting the basics of Python.
