Abstract :
The problem of finding the minimum-length rectilinear Steiner tree that connects a set of points on the boundary of a rectangle is considered. A linear time algorithm for this problem is presented. The algorithm was implemented in C and executed on a Sun3 workstation. Many examples were solved in a fraction of a second. An example with over 250 terminals took 6.5 s.<>
