  3. #C Subject: Pufferless breeder
  4. #C
  5. #N Pufferless breeder
  6. #C Population grows quadratically.
  7. #C A shotgun sends an 8 spaceship salvo eastward every 360 gens.
  8. #C Call the spaceships, from top to bottom, A, B, C, D, D', C', B',
  9. #C and A'.  D and D' are MWSSs; the others are HWSSs.  (The shotgun's
  10. #C output is approximately glide symmetric.)  Every 360 gens, two
  11. #C guns and a kickback reaction are used to create a northeastward
  12. #C glider in front of A and B.  A and B redirect the glider
  13. #C southeastward.  Then C' and D' duplicate it, producing 2 SEward
  14. #C gliders and a block.  The second glider escapes, the block is
  15. #C deleted by D, and the first glider is turned NEward by A' and B'.
  16. #C It is duplicated by C and D, again producing an escaping glider, a
  17. #C block that gets deleted by the next D', and another NEward glider.
  18. #C The latter interacts with the next A and B in the same way as the
  19. #C original glider did, 596 gens later and 118 units farther east.
  20. #C
  21. #C Thus, in gen t, there are approximately  t/360  gliders zigzagging
  22. #C east, each producing 2 more gliders every 596 gens.  So the
  23. #C population is growing by about  5 * 2/596 * t/360  =  t/21456
  24. #C cells per generation, and the total population is about  t^2/42912.
  25. #C The gliders occupy a nonconvex quadrilateral with vertices at
  26. #C (approximately)  (0,0),  (t/4,t/4),  (59t/298,0),  and  (t/4,-t/4).
