Key Concepts

Chromatic Polynomial

The chromatic polynomial of a graph is a function that counts the number of ways to color the vertices of the graph using a given number of colors such that no two adjacent vertices share the same color. It encapsulates in a polynomial form fundamental combinatorial information about the graph’s coloring properties.

Graph Coloring

Graph coloring is the process of assigning labels (or colors) to elements of a graph, such as its vertices, in such a way that adjacent vertices receive different colors. This concept is central in understanding various problems in graph theory, including scheduling, partitioning, and frequency assignment problems.

Deletion-Contraction Algorithm

The deletion-contraction algorithm is a recursive procedure used to compute the chromatic polynomial of a graph. It involves choosing an edge and creating two simpler graphs: one by deleting the edge and the other by contracting it, effectively merging its endpoints. The chromatic polynomial is then derived using a recurrence relation based on these two cases.

Cube Graph

The cube graph, typically denoted as Q3, represents the vertices and edges of a three-dimensional cube. It is a regular graph with specific combinatorial structure and symmetry properties. Understanding its structure is crucial when applying algorithms like deletion-contraction to compute its chromatic polynomial.
