oai:localhost:PNK-73792023-03-31T06:47:48Z Characterizations and Directed Path-Width of Sequence Digraphs Frank, Gurski Carolin, Rehs Jochen, Rethmann input digraph G = (V,A) NP-hard problem CC BY Computing the directed path-width of a directed graph is an NP-hard problem. Even for digraphs of maximum semi-degree 3 the problem remains hard. We propose a decomposition of an input digraph G = (V,A) by a number k of sequences with entries from V, such that (u,v) ∈ A if and only if in one of the sequences there is an occurrence of u appearing before an occurrence of v. We present several graph theoretical properties of these digraphs. Among these we give forbidden subdigraphs of digraphs which can be defined by k = 1 sequence, which is a subclass of semicomplete digraphs. 2023-03-31T06:47:44Z 2023-03-31T06:47:44Z 2023 Book https://link.springer.com/article/10.1007/s00224-022-10104-w https://dlib.phenikaa-uni.edu.vn/handle/PNK/7379 en application/pdf Springer |
