Modeling and Control of Large-Scale Adversarial Swarm Engagements
We theoretically and numerically study the
problem of optimal control of large-scale autonomous
systems under explicitly adversarial conditions, including
probabilistic destruction of agents during the simulation.
Large-scale autonomous systems often include an adver sarial component, where different agents or groups of
agents explicitly compete with one another. An important
component of these systems that is not included in current
theory or modeling frameworks is random destruction of
agents in time. In this case, the modeling and optimal
control framework should consider the attrition of agents
as well as their position. We propose and test three
numerical modeling schemes, where survival probabilities
of all agents are smoothly and continuously decreased in
time, based on the relative positions of all agents during
the simulation. In particular, we apply these schemes to
the case of agents defending a high-value unit from an
attacking swarm. We show that these models can be
successfully used to model this situation, provided that
attrition and spatial dynamics are coupled. Our results
have relevance to an entire class of adversarial autonomy
situations, where the positions of agents and their survival
probabilities are both important.ONR SoA programNPS CRUSER progra
A Hybrid, Multi-Agent Model of Foraging Bottlenose Dolphins

10.3182/20090916-3-ES-3003.00046Social behavior of animals can offer solution models for missions involving a large number of
heterogeneous vehicles, such as light combat ships, unmanned aerial vehicles, and unmanned underwater
vehicles. We draw inspiration from the foraging techniques of bottlenose dolphins to address the
problem of heterogeneous multi-agent herding. We produce a hybrid automaton model of the entire
foraging method - search, detect, and capture - where agents are modeled as first-order systems in which
interactions are defined through spatial proximity. Finally, simulations are provided to illustrate that our
model is expressive enough to capture this complex biological phenomenon
