Energ2

Program automatically finds suitable locations for vertices of
given graph, minimizing the system energy.

Input to program:

   1. Type of edges
      u - unweighted edges
      w - weighted edges

   2. Starting positions
      c -  starting positions on circle
      r -  random starting positions

   3. Network file name (without extension (.NET)
      The format is explained in programs DRAW and COORD documentation.

   Output is filename with extension ENG. It can be shown on screen
   or exported to PostScript using program DRAW.
