These programs, need to be run with Python3, so install that as suggested by \link{https://www.python.org/downloads/}.
The package manager {\tt pip} is also necessary for installation of third party graphics libraries such as {\tt NetworkX}. Install that as described here: \link{https://pip.pypa.io/en/stable\-/installing/}.

Now that those tools are available, run the following shell commands to install relevant libraries:
{\tt\obeylines\parindent=1in
\$ pip install networkx
\$ pip install numpy
}

Each file should be executable with ``{\tt python3 \$filename}'', preferably in its local directory. The files can be obtained from the internet with ``{\tt git clone https://github.com/feynmansfedora/appcomb-proj.git}'', assuming {\tt git} is installed. If it is not, it can be cloned from \link{https://github.com/feynmansfedora/appcomb-proj} directly.
