A line connects vertices that appear in the same row, column, or subgrid. This translation allowed the mathematicians to use mathematical tools developed in graph theory to understand sudoku.

This is especially true in graph theory, a field that studies networks of ... There’s a path between any two dots — what graph theorists call vertices — and no path is longer than two line segments, ...

The metric dimension is a key invariant in graph theory that encapsulates the minimal number of reference points, or “resolving sets”, required to uniquely determine the position of each ...

But in theory ... of each node in the graph and assigns it a color. The different colors thus assigned allow the algorithm to ...

Imagine, he said, a graph — a collection of points connected by lines. Ensure that all of ... the problem into the world of graph theory by representing every country as a vertex and connecting two ...

Graph theory is both an area of mathematics ... a diagram consisting of a number of points (nodes, vertices) associated with a number of lines (edges). Each edge is illustrated as a line (or ...
