This repository contains the code, data and experimental scripts needed to reproduce our subgraph isomorphism paper:

Ciaran McCreesh and Patrick Prosser, "A Parallel, Backjumping Subgraph
Isomorphism Algorithm using Supplemental Graphs". To appear at CP 2015.

Parts of this repository are from other authors:

• The vflib/vflib-2.0.6/ directory is the VF Library by the MIVIA Lab Research Group of the University of Salerno. More information can be found at:

  http://mivia.unisa.it/datasets/graph-database/vflib/

• The directedLAD/ directory is Christine Solnon's LAD solver, version 2, which is distributed under the CeCILL-B FREE SOFTWARE LICENSE:

  http://liris.cnrs.fr/csolnon/LAD.html

• The snd/ directory contains the Abscon solver. The txt files in the directory give its licence conditions.

• The instances/ directory contains a subset of Christine Solnon's benchmark instances:

Steps to reproduce the paper:

• Build our code: run 'make' inside the code/ directory, after reading code/README.md for details on compiler requirements and dependencies.

• Build LAD: run 'make' inside the directedLAD/ directory.

• Build the vflib library: run 'make' inside the vflib/vflib-2.0.6/ directory.

• Build the vflib solver: run 'make' inside the vflib/ directory.

• Run the experiments: run 'make TIMEOUT=100000' inside the experiments/ directory. (This will take a loooooong time. If a timeout is not specified, 100s is used instead, which should finish within a few days, but which may cause the charts in the paper to look strange.)

• Copy experiments/results/*.data into the paper/ directory, to replace our experimental results with your own.

• Run 'make' inside the paper/ directory. You will need Gnuplot 5 built with Lua support, and a full TeX Live installation.
