## Newton's method

To numerically find a root of , we may use the Newton’s method. Assuming
the root is at the proximity of , to find a better approximate ,
we consider the tangent line at , which is provided by the

Consider a network , with is a set of focus vertices. Let’s call the multicast sender and the rest the multicast receivers. Given the edges of unit weight, how to find the multicast tree that connects to with minimum total edge weight? This is a generalized minimal spanning tree problem,...
