AD (Attacker Defender) Game

Information Dynamics is a framework for agent-based systems that givesa central position to the role of information, time, and the value of
information.
We illustrate system design in the Information Dynamics Framework by
developing an intelligence game called AD involving attackers,
defenders and targets operating in some space of locations.
The goal of the attackers is to destroy all targets.
Target destruction takes place when the number of attackers in
the target's neighborhood exceeds the number of defenders in this
neighborhood by a value WINNING_DIFFERENCE.
The goal of defenders is to prevent attackers from achieving their goal.
