Python 3 Jupyter Notebook

The following Jupyter Notebooks in Python 3 contain numerous examples, visualization and supplements accompanying the lecture notes. The notebooks require a Python installation with the following required packages:

Python==3.8.11
numpy==1.20.3
matplotlib==3.4.2
networkx==2.6.3
scipy==1.7.1
sympy==1.6.2
ipykernel==6.4.1
ipython==7.27.0
ipython_genutils==0.2.0
ipywidgets==7.6.5
ipympl==0.7.0

The notebooks are also available on binders where they can be run without installing any software.

The notebooks were prepared by Erik Suer, while taking my UCSB course ME/ECE 269 “Network Systems”, during Fall 2021. They are released under the MIT License.

Why I decided to self-publish a print-on-demand book

There are several reasons why I decided to self-publish this book via the print-on-demand service by Kindle Direct Publishing (former Amazon CreateSpace). I appreciate the ability to:

• retain the full copyrights of all the material,

• make the document freely available online in multiple versions (see above),

• retain direct anytime control over the paperback publication costs, retain a majority of the royalties after low fix costs, and set a low price,

• update the book revision at any time (simply re-upload the PDF file, minimal turn-around time, no need for any permission, and never out-of-print), and

• make available a high-quality paperback book through a broad distribution network.

As a combination of this flexibility, I typically polish and enrich the book every time I teach the course.

Similar arguments are presented in the write-up Why I Self-Publish My Mathematics Texts With Amazon by Robert Ghrist
