[Update 09/2023] Our new library CausalDisco provides the baseline algorithms and analytics tools presented here, as well as a new scale-invariant version in a single python package for causal discovery benchmarking.

This repository contains stand-alone implementations of varsortability, sortnregress, and chain-orientation as presented in

[1] Reisach, A. G., Seiler, C., & Weichwald, S. (2021). Beware of the Simulated DAG! Causal Discovery Benchmarks May Be Easy To Game.

For a basic experimental set-up for the comparison of causal structure learning algorithms as shown in the same work, see the VarsortabilityExperimentSuite repository.

To run, perform the following actions within the /src directory:

1. Install dependencies by running ./install.sh in this directory.
2. For varsortability run source env/bin/activate; python varsortability.py in the current directory.
3. For sortnregress, run source env/bin/activate; python sortnregress.py in the current directory.
4. For chain-orientation
   • run source env/bin/activate; python chain_orientation.py in the current directory (may take some time).
   • run source env/bin/activate; python chain_orientation_three_vars_symbolic.py in the current directory (may take some time).
