Old versions of DDLab and documentation
have been released as follows -- click to download:

• Nov 2008 -- multi-value release. Many small but significant improvements and bug fixes. Vector PostScript is now available for most DDLab graphic output: space-time patterns, attractor basins, network graph and jump graph.

  Linux/PC: compiled in Ubuntu 6.06.
  Mac: compiled in Mac OSX 10.4.11 (Run from X11).
  Cygwin/Windows/PC: Cygwin/X is a Linux environment running in Windows. Cygwin/X must be installed with the default packages plus xorg-x11-base, xorg-x11-devel, xorg-x11-fnts.
  DOS/PC: compiled with Watcom C version 11.

• Nov 2005 -- multi-value release -- see new features Dec 2004.
  New features include: outer-totalistic rules, Reaction-Diffusion dynamics (excitable media), scrolling 2d space-time patterns, and other new options, improvements, revisions and bug fixes.

  The ddlab files, and the files in dd_extra.tar.gz, should be in the same directory.

• Dec 2003 -- version m04 -- the first multi-value release -- see new features Dec 2003.
  This is a major update. The most significant changes were: Generalizing all aspects of DDLab for multi-value logic (up to 8 values or colors), instead of just Boolean logic (0,1).
  Click here for some examples.

  Constraining DDLab to run forward only for two types of totalistic rules, which allows larger neighborhoods (up to k=25). In 2d the neighborhoods are predefined to make both square or hexagonal lattices. Many interesting "life"-like and other complex dynamics can be found in this constrained rule-space in 1d, 2d and 3d, including gliders, gliders-guns, self-replication, spirals and predator-prey dynamics. Some amazing examples are provided. Click here for details and instructions for running these complex rules.
