Advanced Techniques for Graph Colouring
In this chapter, we review many of the algorithmic techniques that can be used for the graph colouring problem. The intention is to give the reader... -
Graph Modification for Edge-Coloured and Signed Graph Homomorphism Problems: Parameterized and Classical Complexity
We study the complexity of graph modification problems with respect to homomorphism-based colouring properties of edge-coloured graphs. A...

Linear-Time Graph Programs for Unbounded-Degree Graphs
Achieving the complexity of graph algorithms in conventional languages with programs based on graph transformation rules is challenging because of... -
Introduction to Graph Colouring
In mathematics, a graph can be thought of as a set of objects in which some pairs of objects are connected by links. The interconnected objects are... -
Reducing Graph Parameters by Contractions and Deletions
We consider the following problem: for a given graph G and two integers k and d , can we apply a fixed graph operation at most k times in order to...

Graph Theory
This chapter discusses graph theory where a graph G = (V, E) consists of vertices and edges. It is a practical branch of mathematics that deals with... -
Injective Colouring for H-Free Graphs
A function \(c:V(G)\rightarrow \{1,2,\ldots ,k\}\)... -
The Complexity of Star Colouring in Bounded Degree Graphs and Regular Graphs
A k-star colouring of a graph G is a function $$f:V(G)\rightarrow... -
Colouring Graphs of Bounded Diameter in the Absence of Small Cycles
For \(k\ge 1\) , a k-colouring c of... -
On the Complexity of Colouring Antiprismatic Graphs
A graph G is prismatic if for every triangle T of G , every vertex of G not in T has a unique neighbour in T . The complement of a prismatic graph is...

Colouring Graphs with No Induced Six-Vertex Path or Diamond
The diamond is the graph obtained by removing an edge from the complete graph on 4 vertices. A graph is (... -
Quantum Circuit Compilation for the Graph Coloring Problem
In this work we investigate the performance of greedy randomised search (GRS) techniques to the problem of compiling quantum circuits that solve... -
Deterministic Graph-Walking Program Mining
Owing to their versatility, graph structures admit representations of intricate relationships between the separate entities comprising the data. We... -
Colouring (Pr + Ps)-Free Graphs
The k -Colouring problem is to decide if the vertices of a graph can be coloured with at most k colours for a fixed integer k such that no two...

Colouring simplicial complexes via the Lechuga–Murillo’s model
Lechuga and Murillo showed that a non-oriented, simple, connected, finite graph G is k -colourable if and only if a certain pure Sullivan algebra...
