If 10 people each shake hands with each other, how many handshakes took place? What does this question have to do with graph theory? Answer. This is asking for the number of edges in \(K_{10}\text{.}\) Each vertex (person) has degree (shook hands with) 9 (people). So the sum of the degrees is \(90\text{.}\)

18 wrz 2023 · Discrete mathematics deals with counting individual items, such as whole numbers, rather than continuous quantities like real numbers. Number theory, a major component of discrete math, delves into the properties and behaviors of integers, especially natural numbers and occasionally all integers. Understanding number theory is crucial in comprehend
Any path in the dot and line drawing corresponds exactly to a path over the bridges of Königsberg. Pictures like the dot and line drawing are called graphs. Graphs are made up of a collection of dots called vertices and lines connecting those dots called edges.

An interesting question immediately arises: given a finite sequence of integers, is it the degree sequence of a graph? Clearly, if the sum of the sequence is odd, the answer is no. If the sum is even, it is not too hard to see that the answer is yes, provided we allow loops and multiple edges.
