We fill the (i, j) cell of an adjacency matrix with 1 if there is an edge starting from node i to j, else 0.For example, if there is an edge exists in between nodes 5 and 7, then (5, 7) would be 1. In practice, holding a tree as an adjacency matrix is cumbersome because most nodes may or may not have edges between them, so most …

Generally, col-oring theory is the theory about conflicts: adjacent vertices in a graph always must have distinct colors, i.e. they are in a permanent conflict. If we have a ”good” coloring, then we respect all the conflicts.
