Abstract
  • An interactive computer graphics package was developed for the purpose of solving certain geometric problems in the Euclidean plane. The Geometric Graphics Package provides basic application-independent functions for creating arbitrary views of two-dimensional objects and for supporting interaction between the application program and its user. The application program contains a number of useful functions for our purpose. Our specific application of the Geometric Graphics Package was to develop a heuristic algorithm for the Euclidean Steiner Minimal Tree, known as Steiner's Problem. The problem has been proved to be at least as difficult as any of the NP-complete problems. We present a heuristic algorithm using fixed tension physical relations for the problem. The Geometric Graphics Package is to be used as a tool and to guide us in improving the heuristic.
