Abstract
We consider the Editing to a Graph of Given Degrees problem that asks for a graph G , non-negative integers d,kd,k and a function δ:V(G)→{1,…,d}δ:V(G)→{1,…,d}, whether it is possible to obtain a graph G′G′ from G such that the degree of v is δ(v)δ(v) for any vertex v by at most k vertex or edge deletions or edge additions. We construct an FPT-algorithm for Editing to a Graph of Given Degrees parameterized by d+kd+k. We complement this result by showing that the problem has no polynomial kernel unless NP⊆coNP/polyNP⊆coNP/poly.
