Invited talks

List of HPlan Proceedings

The following are just our (non-archival) proceedings. The individual papers are made available below.

List of HPlan Publications

In the list below you also find some papers with venues different from HPlan. These are papers accepted to HPlan that got simultaneously also accepted at the corresponding venue. So, we only included a link into our proceedings but excluded a new copy. Accordingly, for these double-accepted papers, we list the respective conference venue information instead.

List of papers presented at HPlan

We always offer authors to present their work that has been accepted at other venues. Sometimes, we also invite authors to do so. The list below shows all these works that had been presented at some of our workshops (but not submitted as paper, and hence not been reviewed by us).

Please also note that papers are listed by publication year, not by presentation year. Some papers have been presented not in the same year, but later. If you are curious in which HPlan edition a paper had been presented, this is listed in the bibtex's keywords.
