In graph theory, the handshaking lemma is the statement that, in every finite undirected graph, the number of vertices that touch an odd number of edges is even. For example, if there is a party of people who shake hands, the number of people who shake an odd number of other people's hands is even. [ 1 ]
The formula implies that in any undirected graph, the number of vertices with odd degree is even. This statement (as well as the degree sum formula) is known as the handshaking lemma. The latter name comes from a popular mathematical problem, which is to prove that in any group of people, the number of people who have shaken hands with an odd ...
The undirected route inspection problem can be solved in polynomial time by an algorithm based on the concept of a T-join.Let T be a set of vertices in a graph. An edge set J is called a T-join if the collection of vertices that have an odd number of incident edges in J is exactly the set T.

The Office of the Solicitor General of the Philippines (Filipino: Tanggapan ng Taga-usig Panlahat), formerly known as the Bureau of Justice, is an independent and autonomous office attached to the Department of Justice. The OSG is headed by Menardo Guevarra. The Office of the Solicitor General is the "law firm" of the Republic of the Philippines.
By Kathleen Elkins and Skye Gould In Brazil and the United States, a firm handshake is expected. This would be off putting in the UK, as the British like to greet each other with a lighter handshake.
The Petersen graph is the smallest snark. The flower snark J 5 is one of six snarks on 20 vertices.. In the mathematical field of graph theory, a snark is an undirected graph with exactly three edges per vertex whose edges cannot be colored with only three colors.
The Huffington Post spoke with psychology professors about what this may mean. Florin Dolcos, a University of Illinois associate psychology professor and faculty member at the Beckman Institute's ...
