The abstract extension for sets which minimize the rectilinear crossing number is completed for n up to 18. As meanwhile has been proven for n=18 there is only one unique optimal set. But there are 409002 different abstract order types for n=17 points which obtain the minimum number of 798 crossings. Currently we check whether all these abstract order types can be realized as point sets. In fact we already know that many of them can, and we conjecture that all those sets are realizable.

The time you have to return results for new workunits has been decreased to 24 hours. The reason is that we try to minimize the number of workunits being in progress as we will upgrade the server very soon.
