A function is a rule that is applied to one set of values to give another set of values. A function can be illustrated on a graph - points are plotted as coordinates and joined by either a ...

The statistical physics of graphs and partition functions represents a vibrant intersection of graph theory, statistical mechanics and computational complexity.
