In a recent article, mathematicians explain the use of tools from the branch of mathematics called graph theory to systematically analyze Sudoku puzzles. They also find that analyzing Sudokus ...

In the sudoku graph, this would mean a properly solved puzzle would have no two nodes connected which are the same color—since connections only run along row, columns, and throughout subgrids.

I was inspired by a youtube video from Polylog, discussing Sudoku and how it relates to graph theory. I did not realize it was possible to solve using coloring algorithms, so I decided to give it a ...

The graph below shows the total number of publications each year in Graph Coloring and Planar Graphs. References [1] 2-Distance Choosability of Planar Graphs with a Restriction for Maximum Degree .

Since no row, column, or 3 by 3 subgrid can contain more than one instance of each number, the graph will have no connected nodes of the same color. (For example, suppose we represent 1 with red.

Graph colouring remains a central topic in graph theory, providing the mathematical framework for assigning colours to the elements of a graph under specific constraints. In particular, the ...
