We present an automated algorithm selection method based on machine learning for the graph coloring problem (GCP). For this purpose, we identify \(78\) features for this problem and evaluate the performance of six state-of-the-art (meta) heuristics for the GCP. We use the obtained data to...
Graph Coloring Problem Graph coloring (also called vertex coloring) is a way of coloring a graph’s vertices such that no two adjacent vertices share the same color. This post will discuss a greedy algorithm for graph coloring and minimize the total number of colors used. Job Sequencing Problem...
在图的着色问题中,graph_coloring_algorithm算法是解决这类问题的常用方法之一。该算法的基本思想是将图的所有顶点按照某种规则分配颜色,使得同一颜色的所有顶点之间没有边相连。具体来说,算法首先将每个顶点分配一个颜色,然后从第一个顶点开始,依次为每个未着色的顶点选择与其相邻的已着色顶点颜色相同的颜色,这样就能...
Feature ✅ Description Welsh Powell is used to implement graph labeling/coloring; it is an assignment of labels traditionally called "colors" to elements of a graph subject to certain constraints. Example The program will basically take a...
problem which, to a certain extent, avoids symmetry. We studied the facet structure of the 0/1-polytope associated with it. Based on these theoretical results, we present now a Branch-and-Cut algorithm for the graph coloring problem. Our computational experiences compare favorably with the well...
Since COA at first was presented for solving continuous optimization problems, in this paper we use the COA for the graph coloring problem, we need a discrete COA. Hence, to apply COA to discrete search space, the standard arithmetic operators such as addition, subtraction and multiplication ...
In this study, we presented an exact cutting plane algorithm for the selective graph coloring problem in perfect graphs, which is a generalization of the method presented in Şeker et al. (2019). We also introduced an algorithm to generate random perfect graphs, which, to the best of our ...
