Model of a Firefly Swarm

Using techniques of swarm modeling, it is possible to make a somewhat unrealistic model of firefly behavior.
Concretely, the following differential equations that describe the velocity change of firefly in a swarm of fireflies are solved in a discrete time-step approximation.
For a swarm of fireflies, the parameters and are the interaction strengths, and are the correlation lengths, α and β are the interaction power laws, is the air resistance, and the random variable ξi is interpreted as wind turbulence.
