#### Ex2: SIR model

##### Rolf Widmer

This is a simple SIR infectious diseases 3 stock model with Susceptibles, Infectives and Recovereds stocks. In the initial description the R signified Removed and could include Deaths, Recovered with immunity to infection (Resistant) or those who had fled the epidemic. Note the need to initiate the epidemic by adding a pulse of a single infected person at time 0.

#### Lotka-Volterra model

##### Rolf Widmer

**Prey**

dx/dt = αx - βxyThe prey reproduces exponentially (αx) unless subject to predation. The rate of predation is the chance (βxy) with which the predators meet and kill the prey.

**Predator**

dy/dt = δxy - γy
