Let [math]\displaystyle{ \,G = (V(G),E(G)) }[/math] be a graph. The set [math]\displaystyle{ \,S }[/math] of vertices is called a [math]\displaystyle{ \,(t,i,j) }[/math]-cover if every element of [math]\displaystyle{ \,S }[/math] belongs to exactly [math]\displaystyle{ \,i }[/math] balls of radius [math]\displaystyle{ \,t }[/math] centered at elements of [math]\displaystyle{ \,S }[/math] and every element of [math]\displaystyle{ \,V \setminus S }[/math] belongs to exactly [math]\displaystyle{ \,j }[/math] balls of radius [math]\displaystyle{ \,t }[/math] centered at elements of [math]\displaystyle{ \,S }[/math].
