Wolves and Rabbits

[spudtater]

While writing up my C.V., I recalled an Excel spreadsheet I had done during A-Level Computing: it was a simple application that simulated a population of rabbits and a population of wolves. The rabbits would breed, die of natural causes or be eaten. The wolves would breed, die of natural causes or of hunger. My implementation illustrated a number of interesting factors, including chaotic behaviours. I was wondering whether I still had the l33t Excel skillz to recreate the application. Well, the short answer is "yes".   8^)

For anybody interested, you can download it from my website:

• zipped Excel format
• unzipped Excel format — 89k
• zipped XML format — no graph or macros

It's not particularly accurate or fancy, but it shows some interesting behaviours. Fill in parameters on the first page, and observe their effects on the last page. It's a bit fiddly, but you can manage sets of parameters such that they don't all die... that often.

Have fun!
