Title: History of Arimaa rules
Post by deep_blue on Nov 6^th, 2019, 7:09am

Is there a history page of how the Arimaa rules changed over time?
I am looking to analyze all HvH games with sharp and so I'm wondering if there are old different rules that should be kept in mind. (e.g. a different repetition rule was mentioned, which could crash sharp I guess)

Here is a game that crashed sharp, I am somewhat surprised that in 2005 the rules still were that different (considering the bot of that time, bomb2005 has been a staple ever since): http://arimaa.com/arimaa/games/jsShowGame.cgi?gid=14233&s=b This position should have ended after move 36 by elimination.

According to http://arimaa.com/arimaa/forum/cgi/YaBB.cgi?board=talk;action=display;num=1213818953;start=0, there were three rule changes in mid-2008: elimination, score and repetition becoming illegal rather than a loss. The introduction of elimination removed draws.

Yes, I eventually found that thread too. Though it still leaves the question whether that's the only ever rule change since the creation of game archives. I guess I could implement elimination myself in my analysis program and then see if sharp breaks down on anything else.
