       Avida  is an auto-adaptive genetic system designed primarily for use as
       a platform in Digital or Artificial Life research.  The Avida system is
       based  on  concepts  similar  to  those  employed by the tierra program
       developed by Tom Ray. In lay terms, Avida is a digital world  in  which
       simple  computer  programs mutate and evolve. More technically, it is a
       population of self-reproducing strings with a  Turing-complete  genetic
       basis  subjected  to Poisson-random mutations. The population adapts to
       the combination of an intrinsic fitness  landscape  (self-reproduction)
       and  an externally imposed (extrinsic) fitness function provided by the

       By studying this  system,  one  can  examine  evolutionary  adaptation,
       general traits of living systems (such as self-organization), and other
       issues pertaining to theoretical or evolutionary  biology  and  dynamic
       systems.  The power of Avida is that it gives us a controllable digital
       system in which to study the theories of evolutionary  biology.  Often,
       we  can  study  elements  of  evolutionary theory that are difficult or
       impossible in biological systems.

       Avida is a joint project of the  Digital  Life  Laboratory,  headed  by
       Chris    Adami,    at    the   California   Institute   of   Technology
       ( and Richard  Lenski’s  Microbial  Evolution
       laboratory  at Michigan State university (

       There is a directory with some starting data you can use as a base  for
       your research in /usr/share/alive/.  You just have to copy the contents
       of that directory wherever you  want  and  start  running  avida-viewer
       there.     You   can   find   HTML   documentation   about   avida   in

       There are two viewer programs available, avida-viewer, which is a  text
       mode  one,  using  ncurses  library,  and  avida-qt-viewer,  which is a
       graphics viewer using qt widgets under the X Windowing System.
