WOLFRAM SYSTEM MODELER
This is a placeholder model. It requires the SystemDynamics library.
The following documentation is taken from the main example of the downloadable model. Once you have downloaded all the model dependencies, the model can be downloaded here.
This model explores a typical predator/prey system based on Lotka–Voltera dynamics. This relatively simple system is a good way to get started with understanding population dynamics. A high density of hares will decrease the death rate of the predator, lynx. A higher density of lynx will in turn increase the death rate of the hares.
The included notebook uses a SystemModelParametricSimulate object to interactively explore the model. With the simulation object, different custom visualizations and interactions can be constructed. In the notebook, a parametric plot of the hare versus lynx population is plotted on top of a locator pane where the initial conditions can be chosen. Additional sliders allow you to change parameter values in the model.
These pages show an overview of the example. For the full example, open the accompanying notebook HareLynxPopulation.nb.
