The parameterized complexity of the Elimination problem is studied and it is shown that Elimination is W[1]-hard when parameterized by |V(H)|, even if both input graphs are split graphs, and W[2]- hard when parameterize by |G(G)|−|V( H)|,even if H is a complete graph.

The computational complexity of the problem depends on which graph is assumed to be a tree: it is shown that Elimination can be solved in polynomial time when H is a tree, whereas it remains NP-complete when G is a Tree.
