图着色问题的两个新的进化公式

Two novel evolutionary formulations of the graph coloring problem

V. C. Barbosa, C. A. G. Assis, J. O. do Nascimento

摘要:

我们介绍了两个新的进化公式的问题着色的节点图。第一个公式是基于一个图的色数和它的非循环方向之间存在的关系。它将这些方向视为个体,并借助非常依赖于图的结构及其非循环方向的进化算子来进化它们。第二个公式,不像第一个,不处理一个图在同一时间,而是旨在发展一个“程序”,以颜色的所有图形属于一类的成员都有相同数量的节点和其他共同的属性。从这些公式产生的竞争力已经在一些第二次DIMACS实施挑战基准图上进行了测试,并且与也在这些图上进行测试的其他几种竞争力相比,已经发现具有竞争力。

英文摘要:

We introduce two novel evolutionary formulations of the problem of coloring the nodes of a graph. The first formulation is based on the relationship that exists between a graph's chromatic number and its acyclic orientations. It views such orientations as individuals and evolves them with the aid of evolutionary operators that are very heavily based on the structure of the graph and its acyclic orientations. The second formulation, unlike the first one, does not tackle one graph at a time, but rather aims at evolving a `program' to color all graphs belonging to a class whose members all have the same number of nodes and other common attributes. The heuristics that result from these formulations have been tested on some of the Second DIMACS Implementation Challenge benchmark graphs, and have been found to be competitive when compared to the several other heuristics that have also been tested on those graphs.
