AGGUI: Graphical Interface for AGGs Damien Bargiacchi, Albert Xin Jiang and Kevin Leyton-Brown This program requires Java to run. After downloading, in Windows the program can be executed by double-clicking on the file; in Linux/Windows command line the program can be executed by invoking the command java -jar aggui.jar To create an AGG, first create the action graph using nodes and arrows. click on the center of a node to draw an edge from it. Then create the player classes; for each player class you should then click on it, and select which action nodes are available to this player class. Once the action graph and the players are ready, click the button "Init Payoffs". This will generate an initial payoff table for each node, and you can double click on the node to modify the payoffs. In the Generate menu you can try different example AGGs. If you want to use AGG files created by this GUI as input to GAMBIT, please add a line #AGG as the first line of the file, using a text editor.
