Use typedef int colormapV to define a type that you can then conveniently reference as colormap const color. Adjacency matrix representation of a graph wastes lot of memory space. I will then present bounds on the number of colors needed to color a graph in terms of its extreme adjacency matrix eigenvalues. Adjacency matrix representation of graphs is very simple to implement. Abstract base class of graph. A finite graph can be represented in the form of a square matrix on a computer where the boolean value of the matrix indicates if there is a direct path between two vertices.
Graph coloring with 2 colors exhibits polynomial time behavior whereas optimal solution for whether a graph is colorable for k 2 is NP-complete.
Line 2aii is a command to sum the value of each matrix. For example your neighbors are adjacent to you. In graph theory and computer science an adjacency matrix is a square matrix used to represent a finite graphThe elements of the matrix indicate whether pairs of vertices are adjacent or not in the graph. I will then present bounds on the number of colors needed to color a graph in terms of its extreme adjacency matrix eigenvalues. Line 2aii is a command to sum the value of each matrix. Given an undirected graph represented as an adjacency matrix and an integer k determine whether each node in the graph can be colored such that no two adjacent nodes share the same color using at most k colors.
