[Repast-developer] evolver news

[Nick C. <nic...@ve...>]

Hi,

(I've cc'd repast-developer here because I thought Skye might be
interested in this).

I've just checked in the latest changes to evolver as well as an actual
model. The model is in .../evolver/samples. The model corresponds to the
"baseline model of Uniform Reinforcement" in Skyrms and Pemantle's "A
Dynamic model of social network formation", Proceedings of the National
Academy of Sciences, vol. 97, no. 16. Its a fairly simple model, but all
the behavoir is captured by evolver in only 17 lines of code. The
majority of the code is in the "dump" action in the model which dumps a
probabilty matrix to the screen.

This version of the evolver uses NQPy (Not Quite Python) as its
scripting language and its very easy to use and to follow. If you do run
the model note that it does dump alot of stuff to the console so be
prepared. Also, you'll need to change the project directory in the
project.
