The following is is meant to have some assumptions made (like "n"). I have been up all night trying to figure this out. It can't be Euler because the vertices can't be >1. It might be Hamilton if I assume that E of G(V,E) is infinte..but how would I get my answer? I would just have sets (e1, e2,...) Could this be a straight directed graph where I just count my vertices? If I substitute n for say...4, then I would have 4 vertices? therefore, 4 light are needed to be ordered? (sounds too simple) Please help guide me in the right direction! 1. A contractor for a Paradise city on the XYZ planet has to order traffic lights for the city.

Please help me with this one! 1. Let G be an undirected graph with n vertices. If G is isomorphic to its own compliment , how many edges must G have?

second posting of a graph theory problem
This is my second attempt at trying to gain some clarity on the following problem: 1. A contractor for a Paradise city on the XYZ planet has to order traffic lights for the city. All streets in the city are straight and infinitely long in both directions. No matter how many streets have the same crossing, there will be a need for only one traffic light per crossing. Knowing only the number of streets n, how many traffic lights the contractor is to order to make sure he will not run out lights. The response from the OTA was: "The fact that thestreets are infinitely long is indeed superfluous and it is simply to suggestthat intersection can take place a... click for more
