L(2,1)—labeling of the bracelet graph
In order to better study the channel assignment problem, a function from the vertex set to the set of all nonnegative integers is generated, that is the L(2,1)—labeling of a graph. Let the least label be zero, the L(2,1)—labeling number of a graph is the smallest number over the spans of all L(2,1)—...
