The '''[[Video game bot|Computer Game Bot]] Turing Test''' is a variant of the [[Turing Test]], where a human judge viewing and interacting with a [[virtual world]] must distinguish between other humans and game bots, both interacting with the same virtual world. This variant was first proposed in 2008 by Associate Professor Philip Hingston<ref>{{Cite web|url=http://philiphingston.com/Homepage/Homepage.html|title=Philip Hingston &#124; Home}}</ref><ref name="turing">{{Cite journal|last=Hingston | publisher=IEEE Transactions on Computational Intelligence and AI in Games|first=Philip | title=A Turing Test for Game Bots | date=September 2009|url=http://www.cs.ucf.edu/~gitars/cap6671-2010/Presentations/turing.pdf}}</ref> of [[Edith Cowan University]], and implemented through a tournament called the 2K BotPrize.<ref name="BotPrize">http://botprize.org</ref>

==Tournament==

The first BotPrize Tournament was held in [[Perth]], [[Australia]], on 17 December 2008, as part of the 2008 IEEE Symposium on Computational Intelligence and Games.<ref name="BotPrize 2008"/><ref>{{Cite web|url=http://www.csse.uwa.edu.au/cig08/|title=2008 IEEE Symposium on Computational Intelligence and Games (CIG'08)}}</ref> Each competing team was given time to set up and adjust their bots to the modified game client, although no coding changes were allowed at that point. The tournament was run in rounds, each a 10-minute death match. Judges were the last to join the server and every judge observed every player and every bot exactly once, although the pairing of players and bots did change. When the tournament ended, no bot was rated as more human than any player.

In subsequent tournaments, run during 2009–2011,<ref>{{Cite web |url=http://botprize.org/2009.html |title=Archived copy |access-date=2013-02-03 |archive-url=https://web.archive.org/web/20130226091236/http://botprize.org/2009.html |archive-date=2013-02-26 |url-status=dead }}</ref><ref>{{Cite web |url=http://botprize.org/2010.html |title=Archived copy |access-date=2013-02-03 |archive-url=https://web.archive.org/web/20121230045906/http://botprize.org/2010.html |archive-date=2012-12-30 |url-status=dead }}</ref><ref>{{Cite web |url=http://botprize.org/2011.html |title=Archived copy |access-date=2013-02-03 |archive-url=https://web.archive.org/web/20121229083121/http://www.botprize.org/2011.html |archive-date=2012-12-29 |url-status=dead }}</ref> bots achieved scores that were increasingly human-like, but no contestant had won the BotPrize in any of these contests.

To date, there have been two successfully programmed bots that passed the Computer Game Bot Turing Test:

* UT^2, a team from the [[University of Texas at Austin]], emphasized a bot that adjusted its behaviour based on previously observed human behaviour and [[neuroevolution]]. The team has made their bot available,<ref>{{Cite web|url=http://nn.cs.utexas.edu/?ut2|title = NNRG Software - UT^2: Winning Botprize 2012 Entry}}</ref> although a copy of [[Unreal Tournament 2004]] is required. A short video of their bot is available on YouTube.<ref>Archived at [https://ghostarchive.org/varchive/youtube/20211209/VwIrZ3X4b6c Ghostarchive]{{cbignore}} and the [https://web.archive.org/web/20140421193458/http://www.youtube.com/watch?v=VwIrZ3X4b6c Wayback Machine]{{cbignore}}: {{cite AV media| url = https://www.youtube.com/watch?v=VwIrZ3X4b6c| title = UT bot kills human judge | website=[[YouTube]]}}{{cbignore}}</ref>

* Mihai Polceanu, a doctoral student from [[Romania]], focused on creating a bot that would mimic opponent reactions, in a sense 'borrowing' the human-like nature of the opponent.

Comments from the winners can be found in detail at the BotPrize website.<ref name="BotPrize"/> These victors succeeded in the year 2012, [[Alan Turing]]'s centenary year.
