Yet, non-planar graphs are abundant in network visualization applications. Therefore, graph layout techniques are needed that optimize readability and comprehensibility of graph drawings in the presence of edge crossings. This chapter deals with aesthetic ideas for improving the appearance of crossings ...
Therefore, whenever it is required to calculate the complexity of a nonplanar graph, the matrix-tree theorem, or some equivalent re-casting of it, should be used, and not the theorem of Gutman et al.convenient as that latter theorem often is when a planar graph is being dealt with. ...
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...
The Bethe-Salpeter equation generated by a « unit » nonplanar graph (with two crossed lines) is studied in two oases of scattering of spinless bosons... AP Costogouris - Il Nuovo Cimento (1955-1965) 被引量: 1发表: 1965年 加载更多来源...
Non-Planar Extensions Of Planar Graphs A graph G is almost 4-connected if it is simple, 3-connected, has at least five vertices, and V (G) cannot be partitioned into three sets A; B; C in such a way that jCj = 3, jAj 2, jBj 2, and no edge of G has one end in A and ...
aWhen the graph is non-planar the problem of finding a globally optimal solution is NP-hard. Therefore, approximation methods are employed. 当图表是非平面的发现时的问题一个全球性地最佳方案是NP坚硬的。 所以,略计方法被使用。[translate]
A Characterization of Planar Oriented Graphs The term "minimal nonplanar subgraph" of a graph G refers to a nonplanar subgraph N of G having the property that each proper subgraph of N is planar. A we... JW Ulrich - 《Siam Journal on Applied Mathematics》 被引量: 11发表: 1970年 加载...
