On Stability of V-Like Formations
  Group behavior has received much attention as a test case of self-organization. There has been much written in recent years to investigate interactions within groups of agents. These agents can be animals moving in an interactive way, such as birds, but can also refer to situations such as people driving in traffic. The models that describe these interactions are able to reproduce different structures and patterns relating to the movement and interaction of the agents involved. The advantages and necessities of this type of analysis in any complex biological, technological, economic, or social system are important and far-reaching. Each model that we will discuss describes interaction between agents.
