This is the artifact for the PODC'19 submission "Automatic Verification of Parameterized Population Protocols".

• Python 3.
• Graph-tool library for Python 3.
• Graphviz with Python 3 bindings.
• Z3 with Python 3 bindings.
• TeX distribution with pdflatex command and geometry, amsmath, booktabs, multirow and siunitx packages for generating a PDF with the table of experimental results (optional).

On Ubuntu 18.04, all dependencies can be installed using the following commands:

echo 'echo "deb http://downloads.skewed.de/apt/bionic bionic universe" >> /etc/apt/sources.list' | sudo bash
echo 'echo "deb-src http://downloads.skewed.de/apt/bionic bionic universe" >> /etc/apt/sources.list' | sudo bash
sudo apt-key adv --keyserver pgp.skewed.de --recv-key 612DEFB798507F25
sudo apt update
sudo apt install python3 python3-graph-tool python3-gv python3-pip
pip3 install z3-solver
sudo apt install texlive-latex-base texlive-latex-recommended texlive-latex-extra texlive-science

• The folder protocols contains several parameterized protocols for flock-of-birds, remainder and threshold.
• The folder src contains the source code for constructing the abstraction, stage graph and checking the termination witness.
• The folder benchmarks contains scripts to reproduce the experimental results from the paper.

The tool can be run on e.g. the basic basic parameterized flock-of-birds protocol as follows, with additional options for more verbose output and inspectable intermediate results:

python3 src/main.py protocols/flockofbirds_basic.ppp -v -o -t stages.pdf -p -a abstraction.pp

The tool will print information on the termination and termination time of the protocol. The file stages.pdf will contain the stage graph afterwards, and the file abstraction.pp the abstraction of the parameterized protocol.

The results table from the paper can be reproduced by running the following command from the main folder:

sh run_benchmarks.sh

Execution of this command should take at most 10 minutes. Afterwards, it will generate a file results.pdf which will resemble Table 1 in the paper.
