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.
