Rectilinear Local Crossing Number

DOWNLOAD Mathematica NotebookDownload Wolfram Notebook

The rectilinear local crossing number of a graph G denoted lcr^_(G), is the minimum local crossing number over all rectilinear drawings of G.

Ábrego and Fernández-Merchant (2017) determined the rectilinear crossing number of the complete graph K_n to be

lcr^_(K_n)={4 for n=8; 15 for n=14; [1/2(n-3-[(n-3)/3])[(n-3)/2]] otherwise.
