C-宽度有界图上的图运算

Graph Operations on Clique-Width Bounded Graphs

Frank Gurski

摘要:

candle-width是一个众所周知的图形参数。许多NP-困难图问题在限制于有限宽度的图时,允许多项式时间解。这同样适用于NLC宽度。本文研究了在各种图操作和图变换下的cn-width和NLC-width的行为。我们根据所涉及的图的连通宽度和NLC宽度,给出了修正图的连通宽度和NLC宽度的上界和下界。

英文摘要:

Clique-width is a well-known graph parameter. Many NP-hard graph problems admit polynomial-time solutions when restricted to graphs of bounded clique-width. The same holds for NLC-width. In this paper we study the behavior of clique-width and NLC-width under various graph operations and graph transformations. We give upper and lower bounds for the clique-width and NLC-width of the modified graphs in terms of the clique-width and NLC-width of the involved graphs.
