These videos show some typical behaviors of agent teams evolved with HyperNEAT for the GECCO 2008 paper, Generative Encoding for Multiagent Learning.  In all videos, the predators are located at the bottom and the prey are the blue squares in the center.  Note that predators cannot see each other so all coordinated activity is completely dependent upon assigned roles.

Heterogeneous Agents Attacking Symmetrically:

The top video shows the predators executing an almost perfectly symmetric attack against two variations of the triangle formation, while the bottom video shows a symmetric attack against a diamond shaped formation.

Heterogeneous Agents Corralling the Prey:

The top video shows the outside predators executing symmetric corralling while the center agents act as a fence to trap the prey, who are initially in a square formation.  The bottom video shows an example of asymmetric corralling against a triangle formation of prey.

Heterogeneous Agents Hunting the Prey:

The top video shows two predators teaming up to hunt all of the prey in the diamond formation.  The bottom video shows another example with multiple hunting parties against the triangle formation.

Homogeneous Team Tactics:

The top video shows the tactics used by almost all homogeneous teams in the experiment.  Each agent on the team chases a prey in a circle, if two circles intersect there's a chance they can capture the prey.  This method is inefficient and can sometimes lead to unwinnable scenarios like in the bottom video.

Additional Heterogeneous Behaviors:

The top video shows an interesting role differentiation wherein the central agents twitch rapidly, while the outer agents glide smoothly.  The bottom video shows another interesting corralling example.
