Rectilinear Crossing No. Project

Anything related to Rectilinear Crossing No.

Rectilinear Crossing No. Homepage

Description:
Many questions in computational and combinatorial geometry are based on finite sets of points in the Euclidean plane. Several problems from graph theory also fit into this framework, when edges are restricted to be straight. A typical question is the prominent problem of the rectilinear crossing number (related to transport problems and optimization of print layouts for instance): What is the least number of crossings a straight-edge drawing of the complete graph on top of a set of n points in the plane obtains? Here complete graph means that any pair of points is connected by a straight-edge. Moreover we assume general position for the points, i.e., no three points lie on a common line.

Please cancel all the old workunits, currently we crunch the W0q series for testing the system. I will inform you asap when the error is eliminated.

January 9, 2008
We have some trouble with the new workunits and currently we debug the hole stuff. The server might be done now and then today. Sorry.


If anyone has it running.

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.

CRUNCH OR CANCEL: Dear users! Next week we will update the server-version of this project. Therefore all current workunits will be canceled on monday. Please finish all your computations until sunday. See the fora for more information.
