WebDefinition 1. A Hamilton's cycle is a graph cycle in which every vertex of a graph is passed only once (except the first vertex). Hamilton's path is a graphical path that visits each vertex exactly once. Finding a Hamilton's cycle with a minimum of edge weights is equivalent to solving the salesman problem. Hamilton's graphs are called Hamilton's. WebMar 21, 2024 · Such a sequence of vertices is called a hamiltonian cycle. The first graph shown in Figure 5.16 both eulerian and hamiltonian.
