WebMuch of the work in graph theory is motivated and directed to the problem of planarity testing and construction of planar embeddings. Inversely, much of the development in graph theory is due to the study of planarity testing. Auslander and Parter [AP61], in 1961 and Goldstein in 1963 presented a first solution to the planarity-testing problem.

WebUtility graph K3,3. In graph theory, a planar graph is a graph that can be embedded in the plane, i.e., it can be drawn on the plane in such a way that its edges intersect only at their endpoints. In other words, it can be drawn in such a way that no edges cross each other. [1] [2] Such a drawing is called a plane graph or planar embedding of ...
