PyCX 0.32 is now available! (released on 9/9/2016)
WPyCX 0.31 rev. 2 -- a Python 3.5 port of PyCX -- is now available! (updated on 3/26/2016)
The PyCX Project aims to develop an online repository of simple, crude, yet easy-to-understand Python sample codes for dynamic complex systems simulations, including iterative maps, cellular automata, dynamical networks and agent-based models.

Project Summary on SourceForge.net
Current Version: PyCX-0.32.zip (updated on 9/9/2016) and WPyCX-0.31_rev2.zip (updated on 3/26/2016)
Codes are tested with Anaconda Python 2.7 and 3.5.
Note to Jupyter users (updated on 6/5/2018)
To run PyCX's dynamic simulations from Jupyter, take the following steps:
| 1. In Jupyter's "Files" tab, go to the folder where your simulation code and pycxsimulator.py exist. |
| 2. Open a new Jupyter notebook. |
| 3. Execute "%run abc.py" in the notebook (where "abc.py" should be replaced by the name of your code). |
| 4. For repeated execution of simulations, use the "Kernel" -> "Restart & Run All" option from the top menu. |
Note to Anaconda/Spyder users (updated on 6/5/2018)
To run PyCX's dynamic simulations on Anaconda/Spyder, you may need to disable automatic activation of matplotlib support. To do this, choose "Tools" -> "Preferences" -> "IPython console" -> "Grahics", and then uncheck the "Support for graphics (Matplotlib): Activate support" box. You will need to restart your kernel to make this change into effect.
For repeated execution of simulations, use Ctrl-. or "Consoles" -> "Restart kernel" before running the code again.
What's new in version 0.32?
* The "pycxsimulator.py" GUI module was updated with several bug fixes by Toshi Tanizawa and Alex Hill to make its GUI and visualization more stable.
*
The file name of the Schelling's segregation model was changed to "abm-" to better reflect the nature of the model.
*
Sample codes used in Hiroki Sayama's Open SUNY textbook (http://tinyurl.com/imacsbook) are now included in the "textbook-sample-codes" subfolder.
What's new in version 0.31?
* The graphics backend has been changed from Tix to ttk so that Mac users can run it without installing Tix.
What's new in version 0.3?
* Przemyslaw Szufel & Bogumil Kaminski at the Warsaw School of Economics made a substantial improvement to the "pycxsimulator.py"
GUI module, implementing interactive control of model and visualization parameters.
* Several new sample simulation codes were added.
* PyCX is now distributed under the FreeBSD license (see LICENSE.txt).
