摘要
本文研究偶补图的侧廓问题和填充问题的计算复杂性,证明了:即使对直径不超过2的偶补图,侧廓问题和填充问题也是NP-完全的.
The computational complexity of the profile problem and the fill-in problem is studiedin this paper. Our main results are as follows: The profile problem and the fill-in problem are NPcomplete even for cobipartite graphs with diaxneter at most 2.
