Short: A special type of cellular automata Author: Olivier Martin, voltigeur@worldonline.ch Uploader: Olivier Martin, voltigeur worldonline ch Type: misc/sci Version: 1.x Requires: Amiga OS 3.5+ Architecture: m68k-amigaos Distribution: freeware, sources included This a the light version of Tiger (which can be found under the name of automate8e in the Emperor package, on aminet:dev/c) Both were made with Emperor, the .project file generated by Emperor is also included. A french translation is also included. No installation, just put the drawer wherever you want. Versions for 68020, 68030, 68040 and 68060 (fpu required for all) are provided, but you can compile any version you would like (with StormC 3). This cellular automata was part of my diploma work in Biology. It is supposed to illustrate the creation and evolution of a certain type of vegetation structures called tiger bush, which can be found in various dry countries (Africa, Central America or Australia). The creation and evolution depends mostly on two parameters: the slope and the rainfall. The slope must be low (less than 1.5%) and the rain must be concentrated over a few months only (typical from dry countries). Another important parameter are the termites. They build their houses which have a big impact on the landscape and the slope (you can imagine termite-hills 5 meters high in a nearly flat landscape). As they are getting old and forsaken by the termites, the termite-hills are being degraded by rain, wind or any other ecological parameter. Then the material can be moved up to a certain radius (usually 10 meters). In the cellular automata, you can change the slope, rainfall, number of termite-hills, their maximal radius after destruction, as well the x and y sizes of the simulation, plus the number of generations you want the simulation to run. Contrary as in Tiger (the full version), the images are not saved on disk. When in Tiger all the generations where kept in memory to allow to play them later, in Tiger-light only 2 generations are kept in memory. The memory consumption is thus very small. With Tiger-light you can make it compute as long as you want, but you won't be able to have an animation at the end. Another difference is that you can't put termites. They wouldn't give a nice tiger bush anyway (and I'm not motivated to work on that, it's just giving tiger bush all the time, that's a bit frustrating even though it was supposed to do so). Choose the version that suits you best.
