"This notebook is the computational appendix of [arXiv:1808.01275](https://arxiv.org/abs/1808.01275). We demonstrate how to use a version of branch and bound algorithm, augmentend with the chordal extension technique , to compute the exact ground state energy of classical spin models. We also give the details how to reproduce the numerical results shown in the paper. \n",
"To improve readability of this notebook, we placed the supporting functions to two separate files; please download these in the same folder as the notebook if you would like to evaluate it. The following dependencies must also be available: at least one SDP solver ([SDPA](http://sdpa.sourceforge.net) as an executable in the path or [Mosek](https://mosek.com) with its Python interface installed; cvxopt as a solver is not recommended) together with the [Ncpol2sdpa](http://pypi.python.org/pypi/ncpol2sdpa), [networkx](https://networkx.github.io) and [dwavenetworkx](http://dwave-networkx.readthedocs.io/en/latest/index.html) packages.\n",
