The graph-embedding problem concerns the determination of surfaces in which a graph can be embedded and thereby generalizes the planarity problem.

It was not until the late 1960s that the embedding problem for the complete graphs four-colour map problem, which asks whether the countries on every map can be coloured by using just four colours in such a way that countries sharing an edge have different colours.

The knight’s tour ( number game: Chessboard problems) is another example of a recreational problem involving a Hamiltonian circuit.

Hamiltonian graphs have been more challenging to characterize than Eulerian graphs, since the necessary and sufficient conditions for the existence of a Hamiltonian circuit in a connected graph are still unknown.

The vertices and edges of a polyhedron form a graph on its surface, and this notion led to consideration of graphs on other surfaces such as a torus (the surface of a solid doughnut) and how they divide the surface into disklike faces.

Euler’s formula was soon generalized to surfaces as Euler characteristic).

If there is a path linking any two vertices in a graph, that graph is said to be connected.

A path that begins and ends at the same vertex without traversing any edge more than once is called a A graph is a collection of vertices, or nodes, and edges between some or all of the vertices.
