In this lecture, we discuss the notions of Hamiltonian cycles and paths in the context of both undirected and directed graphs. Hamiltonian Cycles and Paths. Let G be a graph. A cycle in G is a closed trail that only repeats the rst and last vertices.

Hamilton Paths and Circuits Definition : A Hamilton path in a graph is a path that visits each vertex exactly once. If such a path is also a circuit, it is called a Hamilton circuit. •Ex : 21 Hamilton path Hamilton circuit
1. Hamiltonian paths in simple digraphs 1.1. Introduction We shall now study some questions on Hamiltonian paths in digraphs, proving (in particular) Rédei’s theorem on Hamiltonian paths in tournaments. We let N denote the set {0,1,2,. . .}of all nonnegative integers. We recall some basic notions from graph theory: Definition 1.1.1.
Definition 4.2.1: A graph with a spanning path is called traceable and this path is called a Hamiltonian path . A graph with a spanning cycle is called Hamiltonian and this cycle is known as a Hamiltonian cycle .
In Combinatorics, we focus on combinations and arrangements of discrete structures. There are five major branches of combinatorics that we will touch on in this course: enumeration, graph
Hamilton circuits and paths •A Hamilton circuit(path) is a simple circuit (path) that contains all vertices and passes through each vertex of the graph exactly once. •How can we tell if a graph has a Hamilton circuit or path? •Not easily, i.e., in general, in not less than exponential time in the number of vertices
