Abstract

We investigate the parameterized complexity of the graph editing problem called Editing to a Graph with a Given Degree Sequence where the aim is to obtain a graph with a given degree sequence \(\sigma \) by at most k vertex or edge deletions and edge additions. We show that the problem is W[1]-hard when parameterized by k for any combination of the allowed editing operations. From the positive side, we show that the problem can be solved in time \(2^{O(k(\varDelta +k)^2)}n^2\log n\) for n-vertex graphs, where \(\varDelta =\max \sigma \), i.e., the problem is FPT when parameterized by \(k+\varDelta \). We also show that Editing to a Graph with a Given Degree Sequence has a polynomial kernel when parameterized by \(k+\varDelta \) if only edge additions are allowed, and there is no polynomial kernel unless \(\mathrm{NP}\subseteq \mathrm{coNP}/\text {poly}\) for all other combinations of allowed editing operations.
