我们给出了一个线性时间算法,检查两个0-1矩阵之间的同构,服从循环1属性。我们的算法是类似的同构算法的Lueker和Booth的区间图,但PC树,这是无根的,有一个循环的性质,而不是PQ树,这是根。该算法导出了相关图类的线性时间同构算法,包括Helly圆弧图、Γ圆弧图、真圆弧图和凸圆图。
We give a linear-time algorithm that checks for isomorphism between two 0-1 matrices that obey the circular-ones property. Our algorithm is similar to the isomorphism algorithm for interval graphs of Lueker and Booth, but works on PC trees, which are unrooted and have a cyclic nature, rather than with PQ trees, which are rooted. This algorithm leads to linear-time isomorphism algorithms for related graph classes, including Helly circular-arc graphs, Γ circular-arc graphs, proper circular-arc graphs and convex-round graphs.
