Weba "spanning tree", an RST is permitted to have three or more line segments meeting at a point that does not belong to A, called a Steiner point. In fact, it is frequently the case that every optimum RST for A contains one or more Steiner points. The "rectilinear Steiner tree problem" is, given A, to find an optimum RST for A. WebStart with the root and put it inside a forest environment and inside square brackets: \begin {forest} [IP% root % rest of tree will go here ] \end {forest} The rest of the tree consists of one or more smaller trees. These are subtrees of the root node.
