WebHonors Discovery Seminar: Graph Theory, Part II Definition.A graph is planar if we can draw it in the plane without any of the edges crossing. A face of a planar graph is a region bounded by the edges. We say that the region outside a graph is also a face. (For a more senisble version of this: draw your graph on a sphere, and then count the faces.) WebIn graph theory, a vertex cover (sometimes node cover) of a graph is a set of vertices that includes at least one endpoint of every edge of the graph.. In computer science, the problem of finding a minimum vertex cover is a classical optimization problem.It is NP-hard, so it cannot be solved by a polynomial-time algorithm if P ≠ NP.Moreover, it is hard to …

Sometimes you can recover the vertices from ...

WebA closed path in the graph theory is also known as a Cycle. A cycle is a type of closed walk where neither edges nor vertices are allowed to repeat. There is a possibility that only the starting vertex and ending vertex are the same in a cycle. So for a cycle, the following two points are important, which are described as follows:
