Eternal Domination is concerned with protecting a graph against an
infinite sequence of attacks by use of mobile guards located at some of
the vertices of the graph. There are several different models and
varieties of problems depending on (i) whether attacks are at vertics or
edges (if attacks are at edges, the problem is known as the Eternal Vertex
Cover Problem) (ii) whether only one or all guards all allowed ro move in response to an
attack and (iii) whether at most one or more than one guard is allowed on
a vertex at a time.
