Cellular Automata
« on: February 28, 2018, 05:51:17 am »
At IRC this morning the subject of Cellular Automata came up.

Since I am advocating reposting Golden Oldies from NET here is sample of one of my long time favorites, Classic John Conway Life:
Code: QB64: [Select]
  1. _TITLE "Quick Life trans for QB64 11-06.82  2017-11-11by bplus"
  2. ' From: quick life.bas SmallBASIC (not MS) B+ G7 stripped down to favorite setting
  3. '
  4. ' To: the one out there who has checked out Conway's Life the last couple of days.
  5. ' For you, a working version (albeit highly modified) of Conway's Life code in QB64.
  6. '
  7. ' Quote Rules (from Wiki):
  8. ' The universe of the Game of Life is an infinite two-dimensional orthogonal grid of square cells,
  9. ' each of which is in one of two possible states, alive or dead, or "populated" or "unpopulated".
  10. ' Every cell interacts with its eight neighbours, which are the cells that are horizontally,
  11. ' vertically, or diagonally adjacent. At each step in time, the following transitions occur:
  12. ' 1) Any live cell with fewer than two live neighbours dies, as if caused by underpopulation.
  13. ' 2) Any live cell with two or three live neighbours lives on to the next generation.
  14. ' 3) Any live cell with more than three live neighbours dies, as if by overpopulation.
  15. ' 4) Any dead cell with exactly three live neighbours becomes a live cell, as if by reproduction.
  16. ' The initial pattern constitutes the seed of the system.
  17. ' The first generation is created by applying the above rules simultaneously to every cell in the
  18. ' seed—births and deaths occur simultaneously, and the discrete moment at which this happens is
  19. ' sometimes called a tick (in other words, each generation is a pure function of the preceding one).
  20. ' The rules continue to be applied repeatedly to create further generations.
  21. ' (End Quote)
  22.  
  23. ' Alas in practical applications we do not have infinite board to play Life, so at boundries rules
  24. ' break down as neighbor counts are only 5 max on edge and only 3 max at corners.
  25.  
  26. 'This code is very easy to modify into other tests / demos:
  27. ' Try coloring by neighbor counts.
  28. ' Try other rules besides Classic 2,3 neighbors = survive, 3 neighbors = birth.
  29. ' Try regenration along the borders every other generation, which causes symetric beauties!
  30. ' Change an = the number of cells per side, even amounts that divide 700 (pixels per board side) work best.
