A planar straight line embedding of a planar graph is a planar embedding in which only straight line segments are used to connect the graph vertices. The Fáry theorem established that every planar graph has a planar straight line embedding with noncrossing edges, and such embeddings (with rectilinear crossing number 0) are sometimes known as a Fáry embedding. A planar straight line embedding of a planar graph can be constructed in the Wolfram Language using the PlanarEmbedding option to GraphLayout or in the Wolfram Language using PlanarGraph[g]. de Fraysseix et al. (1988) give an algorithm for constructing a planar straight line embedding for a planar graph of order n by placing the vertices on a (2n - 4)×(n - 2) grid.
We guarantee you’ll find the right tutor, or we’ll cover the first hour of your lesson.
Club Z! has connected me with a tutor through their online platform! This was exactly the one-on-one attention I needed for my math exam. I was very pleased with the sessions and ClubZ’s online tutoring interface.
My son was suffering from low confidence in his educational abilities. I was in need of help and quick. Club Z! assigned Charlotte (our tutor) and we love her! My son’s grades went from D’s to A’s and B’s.
I’ve been using Club Z’s online classrooms to receive some help and tutoring for 2 of my college classes. I must say that I am very impressed by the functionality and ease of use of their online App. Working online with my tutor has been a piece of cake. Thanks Z.
Jonathan is doing really well in all of his classes this semester, 5 A’s & 2 B’s (he has a computer essentials class instead of PLC). In his Algebra class that Nathan is helping him with he has an A+.
Sarah is very positive, enthusiastic and encourages my daughter to do better each time she comes. My daughter’s grade has improved, we are very grateful for Sarah and that she is tutoring our daughter. Way to go ClubZ!
