چکیده

A graph G = (V,E) consists of two sets V and E. The elements of V are called the vertices and the elements of E the edges of G. Each edge is a pair of vertices. For instance, the sets V = {1, 2, 3, 4, 5} and E = {{1, 2}, {2, 3}, {3, 4}, {4, 5}} define a graph with 5 vertices and 4 edges. Graphs have natural visual representations in which each vertex is represented by a point and each edge by a line connecting two points.

This is an early draft and, with any luck and copious funding, some of this can be made into a publishable work and some will just remain as notes. Please do not distrib...

Notes on NP Completeness

Here are some notes which I wrote to try to understand what NP completeness means. Most of these notes are taken from Appendix B in Douglas West’s graph theory book, and also from wikipedia. There’s nothing remotely original about these notes. I just wanted all this material to filter through my brain and onto paper. I also wanted to collect everything together in a way I like. Here’s what thes...
