Quoting the news tidbit I just posted, to make sure all developers know about this somewhat substantial change... Both FoodBands and the original uniform random distribution of food have been replaced with Matt Whitehead's new FoodPatch objects. They allow any number of rectangular or elliptical patches, with any amount of food and arbitrary food growth rates distributed uniformly, with a linear probability distribution, or with a Gaussian/normal probability distribution, either probabilistically or rigidly/deterministically. A new worldfile (now version 19) has been checked in that shows how to use them (although a known problem with complexity as a fitness function will make the code crash after a fairly short time with this worldfile). A FoodPatchNotes.pdf document from Matt on how food patches were designed and how they work is in the docs/ directory. - larryy P.S. If SourceForge's servers don't strip it, I'm attaching a "worldfile_patchtest" that is kind of fun to run, once, just to see very different and dramatic patch densities, shapes, and growth rates. |
