In graph theory, a planar graph isa 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. ...

stereochemistry A0210 Algebra, set theory, and graph theoryIt is emphasized by means of counter-examples that the theorem of Gutman, Mallion and Essam (1983, Molec. Phys., 50, 859), for computing the number of spanning trees in a labelled graph, is generally valid only for planar graph...
A graph is 1- planar if it can be drawn on the plane so that each edge is crossed by no more than one other edge. A non-1-planar graph G is minimal if the graph G - e is 1-planar for every edge e of G. We prove that there are infinitely many minimal non-1-planar graphs ...
Like past QAOA experiments, we study performance for problems defined on the planar connectivity graph native to our hardware; however, we also apply the QAOA to the Sherrington–Kirkpatrick model and MaxCut, non-native problems that require extensive compilation to implement. For hardware-native ...

A graph is said to be planar if it can be drawn in a plane so that no edge cross. Example:The graph shown in fig is planar graph. Region of a Graph:Consider a planar graph G=(V,E).A region is defined to be an area of the plane that is bounded by edges and cannot be further...
Thus, by defining planar layers in {s}, the model can be sliced with non-planar uniform layers parallel to the build platform. Commercial software was used to define these planar layers in {s}. To validate the methodology, two case studies have been defined and validated in a robotized ...
3) non-planar topology 非平面拓扑 1. It is discussed in detail how to implement feature-based non-planar topology for traffic networks to makes up the deficiency of geo-relational design method and planar graph based link-node data structure. 针对基于特征的GIS及交通网络分析对数据结构的要求 ...
