Experimental Repository for "Certifying Without Loss of Generality Reasoning in Solution-Improving Maximum Satisfiability"

Experimental repository for "Certifying Without Loss of Generality Reasoning in Solution-Improving Maximum Satisfiability".

The directory is structured as follows:

data: Data that has been processed into CSVs and the scripts to analyse the experiments.

plots: The plots generated from the data that are used in the paper.

raw_data: The raw data logs for the experiments and scripts to extract relevant data from the logs.

source_code: Source code for the checker VeriPB and the MaxSAT solver Pacose in the different variants used for the experiments. The Pacose version in PacoseMaxSATSolver-baseline is Pacose without proof logging, the version in PacoseMaxSATSolver-certified is Pacose with proof logging. Proof logging using only assumptions for the coarse convergence can be enabled via the option --WithAssumptions.

Install Requirements

To install and run the MaxSAT solver Pacose and the pseudo-Boolean proof checker VeriPB your need to have the following components installed:

Python 3.6.9 or higher with pip and setuptools installed

g++ 7.5.0 or higher

libgmp

These can be installed in Ubuntu / Debian via

sudo apt-get update && apt-get install \
python3 \
python3-pip \
python3-dev \
g++ \
libgmp-dev
pip3 install --user \
setuptools

How to Run?

The MaxSAT solver Pacose can be compiled using the install script in PacoseMaxSATSolver-certified:

./install

To run Pacose with proof logging, where the proof should be written to proof.pbp, run the following command in the PacoseMaxSATSolver-certified directory:

./bin/Pacose --proofFile proof.pbp instance.wcnf

The proof can be checked with VeriPB. To compile VeriPB run the following in the VeriPB directory:

pip install .

To check the proof with VeriPB, run the following inside the PacoseMaxSATSolver-certified directory:

veripb --wcnf instance.wcnf proof.pbp
