Python package for solving maximum entropy problems with a focus on the pairwise maximum entropy model, also known as the inverse Ising problem.

See "ipynb/usage_guide.ipynb" for usage documentation and examples.

There is an accompanying guide on arXiv: [https://arxiv.org/abs/1801.08216].

This package is available on PyPI for Linux and MacOS. It can be installed by running

pip install coniii

If you have trouble using pip and PyPI, then you can always build this from source. Download this package from GitHub and move the coniii folder to wherever you would like to have the module. Inside coniii, you must run

python setup_module.py build_ext --inplace

If you would like to use the Enumerate solver for system sizes greater than 9, you must run exact.py to write those files yourself. This can be run from the install directory. If you do not know where the installation directory is, you can find it by opening up an iPython notebook and running

import coniii
coniii.__path__

Once inside the install directory, you can run in your bash shell

python exact.py [N]

where [N] should be replaced by the size of the system.
