We collected various benchmark domains from the planning community by reaching out via mailing list and contacting specific groups and authors.

Not all domains have been selected for the final evaluation for various reasons. We thus ended up in having two distinct benchmark repositories:

Note that many of the submitted domains (selected or not) come with short descriptions that we included in out IPC booklet.

If you have another HTN domain and would like to share it with the community, please contact the organizers! Also long after the competition!
