…topological graph theory is the map-colouring problem. This problem is an outgrowth of the well-known 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. Asked...

EFB simplifies the feature bundling problem by framing it as a graph coloring problem (GCP) and employs a greedy algorithm to approximate computations [39]. Additionally, EFB incorporates the histogram algorithm to differentiate between original feature values and bundled features [40]. This technique...
