论文摘要
我们介绍了签名图中的缺陷概念。颜色的不足是未使用的颜色的数量。我们对2个色素图的缺陷进行了分类。关于3个纹章签名的图的最小和最大缺陷存在四个决策问题。我们使用多项式时间算法回答了其中两个,以确定3色符号的最大缺陷。
We introduce the concept of deficiency in signed graphs. The deficiency of a coloration is the number of unused colors. We classify the deficiency of 2-chromatic graphs. There are four decision problems about the minimum and maximum deficiency of a 3-chromatic signed graph. We answer two of them with a polynomial-time algorithm for deciding the maximum deficiency of a 3-chromatic signed graph.
