In a word, the degree sequence Havel theorem of vertices ~ Definition: the vertex degree sequence {DN} of an undirected graph is given. It is required to determine whether a simple undirected graph can be constructed. Analysis: The greedy method is to sort the vertices by degree from large to small each time, retrieve the vertices vi with the highest

First, the conceptUnlike the "degrees" in graph theory, the degree of the tree is defined as: the number of children in the root tree T, node X is called the degree of X. That is: in the tree, the node has a few bifurcation, the degree is a few. A useful little formula: node in the tree = Total Fork number +1. (The number of forks here is the sum of the degrees

Problem Description:Given a list of n natural numbers D1, D2,..., dN, show how to decide in polynomial time whether There exists an undirected graph G = (V, E) whose node degrees is precisely the numbers D1, D2,,d N. G should not contain multiple edges between the same pair of nodes, or "loop" edges with both endpoints equal to The same node.The problem is judging whether a simple graph can be formed from a sequence of degrees. The first statistic is whether the sum of the degrees is even, whic
