This is the Salzburg Database of Geometric Inputs, a repository of graphs for testing and benchmarking your computational geometry implementations.
All data can be found in the db directory. It can be downloaded either
directly or with git-annex using
git clone https://sbgdb.cs.sbg.ac.at/db/.git followed by
git annex get in the
working copy directory. Git annex enables you to also get specific files only.
At the moment, our repository consists of random simple polygons, with and without holes, produced with different generators. Furthermore, we have instances of specific polygons such as the Koch snowflake.
The latest release of the data is
released on May 7, 2020. This data-set is fixed and will not see updates.
It can also be retrieved from zenodo; its persistent identifier
Future updates will happen in the work-in-progress directory
which started as a copy of the previous release. In time, this data-set will
become the next release.
Citing this dataset

We also provide BibTeX snippets.
Most graphs are edge weighted with random weights. This is for users who would like to use and test their code with weighted input. Users are of course free to ignore the weights and assume unit weights if it makes sense for their use-case.
