Abstract

Two rectilinear Steiner spanning tree algorithms are presented, proven to be correct, and examined with regard to their complexity. It is shown that their worst case efficiencies are merely 1.5 times the optimum solution. These algorithms, when experimentally compared to existing algorithms, excel. They in fact produce the best solutions over 80% of the time and are never more than 1% from the best solution found.
