Below, enter an input graph with at most 100 nodes and 200 edges, as well as your name, affiliation and e-mail address. We will preprocess the graph by separating the biconnected components and perform non-planar core reductions. The crossing number of each reduced component will be computed.

You will receive a visualization of the non-planar biconnected components, the non-planar core reduction of each component, an optimal planarization of each component, and a proof file for each component containing all required information to comprehend that there cannot be a better solution.

We support a variety of graph formats but recommend to use GML.

Please note that the above data will be stored exclusively for scientific purposes.
