Game Bots

I have been researching game bots (robots) with educational applications and
I cannot find any information! Does anyone have suggestions? I have searched
ERIC
using the key words Artificial Intelligence, Agents, Bots, Data Mining but cannot
find any specific reference to educational Game Bots. The Game Bots I have found
are either of the violent game type, shopping and/or searching and chatterbots
with question and answer capability. Educationally, the Artificial Intelligence
articles in ERIC focus on algorithmically generated math programs and phonics
programs for language development (among others). Any suggestions?
