The dichotomy conjecture for the parameterized embedding problem states that the problem of deciding whether a given graphGfrom some classof “pattern graphs” can be embedded into a given graphH(that is, is isomorphic to a subgraph ofH) is fixed-parameter tractable ifis a class of graphs of bounded tree width and-complete otherwise.Towards this conjecture, we prove that the embedding problem is-complete ifis the class of all grids or the class of all walls.
