This means that all vertices corresponding to the (0,0) grid coordinate should be tagged.

On a valid solution, the following things should happen:

No boundary vertices should be tagged
No vertices connected by an edge or a quad diagonal to a tagged vertex should be tagged
All boundary vertices should have one vertex connected by an edge or a diagonal tagged
