Constant Approximation for Broadcasting in ,-cycle Graphlacing a series of calls along the edges of the graph. Every time the informed vertices aid the originator in distributing the message. Finding the broadcast time of any vertex in an arbitrary graph is NP-complete. The problem is NP-Complete for even more restricted classes of graphs, such as for 3-
