ANN: Pyarie, modular modeling system

[John Metta]

I'd like to announce Pyarie, a modular modeling environment.

Pyarie provides an environment for defining and solving systems of 
ordinary differential equations. It was developed for my use in 
hydrologic and ecological modeling, but is being used to model both 
chemical and aeronautical systems amoung others.

Pyarie is defined to allow modeling in a programming environment with 
minimal initial programming skill that the user can enter equations into 
a class template and optionally define look-up tables and other 
functions for each state variable. Solver classes are provided and 
optimizers are being implemented now.

Basically, it provides a way for non-programmers to create and run 
models without using "black box" modeling environments. The system is 
highly extendable and can be used as either a functional environment for 
the non-programmer, or similiarly to a Python module for the programmer.

Pyarie is housed on SourceForge, with a homepage at 
http://pyarie.wikisophia.org

The Pyarie-users mailing list is live for help and discussion.

Cheers,
