| BS1 Specs show 256 bytes program size |
This is the lite version of TINY AI. The Tricore version of Tiny AI is now available as TriCore_AI.bs1, for copy (see below) and for download at the provided link. The code sets up a life cycle for three cores using the available resources provided by a Parallax BS1.
Download the completed software program in PBASIC at the site below, or simply copy and paste the provided code into the BASIC Stamp editor software. Tricore_AI is the smallest AI program for the series of Stamp processors, fitting into a mere 256 bytes EEPROM. The remarkable attributes of the tricore_ai.bs1 software include self enumerating, determinism, memorizing, remember/recall, nap, dream, sleep, wakeup, talk, listen, know what is heard, work, socialize, hibernate and randomization.
tricore_ai.bs1 software is minimized code with minimal comment length.

' TriCore AI Artificial Intelligence v10.0
' Stamp AI for the BS1 TriCore Supercomputer
' by Dr. Humanoido July 20, 2009
' Code fills the BS1's 256 byte EEPROM
' Code number at end of field indicates number of statements
' A total of 93 program statements
' ---------------------- Directives ---------------------------------
' {$STAMP BS1} ' Self deterministic
' {$PBASIC 1.0} ' Self enumerating
' ---------------------- Descriptions -------------------------------
' Performance of Life Cycle
' 1) read pin 1 and determine id (self enumerating)
' 2) determine computer number based on id range (deterministic)
' 3) remember computer id & number (memorize)
' 4) recall memory of computer id & # (remember)
' 5) nap and pseudo random dream in "Vers Libre" (nap, dream)
' 6) sleep fuzzy clock - its computer number in seconds (sleep)
' 7) wake to send its computer number and id (wakeup, talk)
' 8) Listen for others' computer numbers (listen)
' 9) if heard, remember other computer numbers and id's (know what is heard)
' 10) do some work, retrieve the other ids... (work)
' 11) go into suspended animation (hibernation)
