Open problems of Paul Erdös in Graph Theory - Chung - 1997 () Citation Context ...be the Turán number of H, i.e. the maximum number of edges that an H-free graph on n vertices may have. The problem of estimating ∣ Fn(H) ∣ has been an object of intense study. Erdős ...
To this end, sections on more advanced topics are included, and a number of interesting and challenging open problems are highlighted and discussed in some detail. Despite this more advanced material, the book has been organized in such a way that an introductory course on graph theory can be...
This paper presents our contribution to graph theory: the classification of two long-standing problems, one into P, and the other into NP-complete; the definition of two full dichotomies, of two classes of problems for which every problem is classified into P or NP-complete. Section 2 ...
“There are still many open questions there,” Benson said. “Some of these impossibility results are interesting because you can’t possibly reduce them to graphs. And on the theory side, if you haven’t reduced it to something you could have found with a graph, it’s showing you that ...
The emphasis clearly is on paths and circuits; indeed, with conjectures and open problems numbering nearly ninety, this chapter can be considered a survey of this area of graph theory. Nonetheless, the chapter is sufficiently comprehensive that it can also serve as an introduction to graph theory...

As with any graph-parallel engine, GraphLab assumes input problems modeled as graphs, in which vertices represe...

solve problems of this type in graph theory. But these results alone have not matched up to the scale of the problem of planning open cast mines. Recently, however, Caccetta and Giannini found a systematic way of eliminating redundant arcs in the graph. For example, in the graph the...
