Abstract

We present our most recent implementation of an individual-based lion population model. The model is built using a structure that includes graphical user interaction and feedback at a fundamental level, to maintain flexibility and ease of use without getting mired in programming details. We describe how object-orientated programming structures may be used to this end. Our structure allows for tight integration between the model and the user interface, including seamless user interaction at any point during the simulation. In addition, the simulation model may be decoupled from the user interface, and large, efficient simulations may be performed. The result is an individual-based model that, despite its complexity, is easy to use, easy to maintain and easy to extend. In fact, it has the potential to be used by a much wider group (including other researchers, managers and conservation advocates) than just the researcher who developed it. We include a discussion of the importance of a robust random number generator in simulation models such as this.
