Min number of edges in a graph

WebCrossing number (graph theory) A drawing of the Heawood graph with three crossings. This is the minimum number of crossings among all drawings of this graph, so the graph has crossing number cr (G) = 3. In graph theory, the crossing number cr (G) of a graph G is the lowest number of edge crossings of a plane drawing of the graph G.

WebThe crossing number of a graph is the minimum number of intersections between edges that a drawing of the graph in the plane must contain. For a planar graph, the crossing number is zero by definition. Drawings on surfaces other than the plane are also studied.
