图的(k,d)-着色问题的一个近似算法(英文)
An Approximate Algorithm for the(k,d)-Coloring Problem
【摘要】 本文讨论了图的(k,d)-着色问题的算法,并给出了一个由四层神经元组成的神经网络算法.当一个图的循环色数已知时(不妨设为k/d),可以利用该算法成功地求出这个图的一个可行(k,d)-着色方案;当一个图的循环色数未知时,可以利用该算法求出这个图的循环色数的近似值.
【Abstract】 In this paper,we discuss the(k,d)-coloring problem of a graph,and propose a four-layer neural network algorithm.Using this algorithm,one can successively find a feasible(k,d)-coloring of the graph with given circular chromatic number;moreover one can use this algorithm to estimate the circular chromatic number of a graph.
