Euler’s number taps into fundamental laws of nature and the universe and is used extensively in Machine Learning algorithms. Euler’s number is: 2.718... ln (e) = 1. this shows how e log graphs fit with base 2 and 10.One more definition of a Hamiltonian graph says a graph will be known as a Hamiltonian graph if there is a connected graph, which contains a Hamiltonian circuit. The vertex of a graph is a set of points, which are interconnected with the set of lines, and these lines are known as edges. The example of a Hamiltonian graph is described as follows:In modern graph theory, an Eulerian path traverses each edge of a graph once and only once. Thus, Euler’s assertion that a graph possessing such a path has at most two vertices of odd degree was the first theorem in graph theory. Euler described his work as geometria situs—the “geometry of position.”11 Des 2021 ... Non Eulerian Graph. 2. Eulerian circuit (or Eulerian cycle, or Euler tour).
