Graph colouring remains a central topic in graph theory, providing the mathematical framework for assigning colours to the elements of a graph under specific constraints. In particular, the colouring ...

A C++ implementation that solves the graph coloring problem using the Pagmo2 library's simulated annealing algorithm. The graph coloring problem is a classic NP-hard optimization problem where the ...

The graph colouring problem, a classic NP-hard challenge, is central to many practical applications such as scheduling, resource allocation and network management. Recent advances have seen the ...

Abstract: Coloring a graph is a known and a classical problem in graph theory. It is also a known NP problem. In a graph G, the solution of coloring a graph is about coloring all the vertices of the ...

This code is a project for the discipline Analysis and Project of Algorithms, in the Federal University of Paraiba, Brazil. In this project, we aim to implement a heuristic to resolve the Graph ...

Four years ago, the mathematician Maria Chudnovsky faced an all-too-common predicament: how to seat 120 wedding guests, some of whom did not get along, at a dozen or so conflict-free tables. Luckily, ...
