[freeciv-ai] Re: [Freeciv-Dev] (PR#9626) RFC: design for AI strategic road building

  As a side note, 'strategic' and 'trade inspiring' road buildig should 
be not totally separate. AI should at least consider another as tie 
breaker between equal tiles when building another.

  Common situation in my games:
  There is two equal (in terms of f/p/t, both before and after road is 
built) tiles within city radius. City is working one of them. I decide 
to build road to tile which is not currently worked as it leads towards 
another city too. I also switch worker to this tile immediately so it 
will be used as soon as road is finished even if I forgot rearrange 
workers later (not concern for AI) and to prevent another city from 
'stealing' this tile.

  I hope this does not mean that whole connection is aborted if there is 
no such route where you can build roads to every tile. Before bridge 
building is invented, rivers may cut such routes.

   o   A              o
   o   x              o
   o   x              o
   o    x             o
   o-----------------Co
   o     x            o
   o      x           o
   o      x           o
   o       B          o


  o   - Ocean
  -   - River
  A,B - Cities we want to connect
  C   - Enemy city
  x   - Road I would build

  Note that even without C, using road round river source would take 
longer than above road.
