 2   Arimaa / Bot Development / New bot: bot_turtle  Aug 18th, 2018, 2:48pm 
Started by mattj256 | Last post by mattj256
I made a bot!  It's really basic, just a simple four-step search.
But it can beat ArimaaBotScoreP1, which was a bucket list item for me.
 
http://arimaa.com/arimaa/gameroom/playerpage.cgi?id=22097
 
As you can see, it recognizes goal in one (always) and one-move captures (usually).
Behind the scenes, I wrote 329 test cases (and counting).
Roughly 2/3 of the tests are related to generating legal moves, including many low-level bitboard operations to check for freezing, adjacent enemies, captured pieces, etc.
 
It's written in Java, there are plenty of inefficiencies, and I've been thinking of starting over from scratch in Go.  But I wanted to make a dent in the bot ladder first.
 
This took me two months (while working full-time) and it was totally worth it!  Looking forward to seeing what great things the community comes up with.  (And, when I have time, hopefully contributing some stuff of my own.)

 3   Arimaa / Off Topic Discussion / Tata Nexon Scores 4-Star in Global NCAP Crash Test  Aug 8th, 2018, 3:29am 
Started by helenruybal | Last post by helenruybal
Tata Nexon has scored a 4-star rating by Global NCAP, which is considered as the global benchmark for evaluating the car safety of newly introduced models. The Global NCAP safety tests indicates that the Nexon achieved the highest adult safety score (13.56/17.00) amongst all the models tested across the Indian market.
 
Speaking about the new feat achieved by the Nexon, Mr Mayank Pareek, President – PVBU, Tata Motors, said, “The Global NCAP results are a reflection of our commitment towards bringing technologically advanced features which are safe yet stylish. With these test results, the Nexon is India's safest compact SUV, after being one of the most awarded models from the Tata Motors’ PV stable. It is a proud moment for all our Nexon customers today. I am delighted and proud of the hard-work put in by the entire team and congratulate each one for this accomplishment.  Our journey to offer best quality products continues."

 4   Arimaa / Off Topic Discussion / Re: Christian Freeling on inventing games (part 2)  Aug 7th, 2018, 12:17pm 
Started by christianF | Last post by christianF
 
Summer in the Netherlands started in May and barring the first three weeks of June it has been unrelenting. I enjoyed it but it has been going on a bit so I'm glad we're bound to go normal. Meanwhile my main occupation has been to keep an eye on the snakes, sunbathing in the garden. Big beach umbrella, lots of coffee and marihuana and good music (optional). No games except for playing Dameo and Storisende (now playable at mindsports) online.
 
However, I'd like to introduce you to a provisional Grand Chess program made by Eric Joyce. It looks great and it's provisional because he plans to implement considerable improvements. At the moment the program is rather slow. Here's a quote from the accompanying mail:
Quote:
A future milestone for this project (and one for which I can maybe earn some school credit) will be to set up a machine learning routine that can cultivate skill at Grand Chess independent of my programmed rules. I plan to attempt this using neural networks.
 
...
 
You had mentioned sharing a link to this implementation on Board Game Geek. There is now something to show, though I would issue the obligatory caveats that seem to accompany every web project: "work in progress," "not done," "under construction," etc. I've done a bit of test-playing before writing you this email, but there are bound to be more bugs to find. Any and all bug reports will be most welcomed, from you or from anyone else. If something does go wrong with the program, a screen shot would help me to reconstruct the position and determine the problem's cause.
 
I had hoped to reach this milestone quite a bit sooner, since I've already written an 8 x 8 Chess engine. The better part of my work on Grand Chess was in fact the discovery of bugs in the 8 x 8 code. It simply took the occasion of a variant on that code to flush those bugs out.

Enjoy Smiley

 5   Arimaa / General Discussion / Re: Handicap system for beginners ?  Jun 22nd, 2018, 8:26am 
Started by pago | Last post by DakotaEverard
Arimaa Fast Rules said about handicap the following:
When one player is more experienced or older than another the games can become one sided. To make the game more
balanced the stronger player can play with a handicap by using one less rabbit or other piece. The stronger the piece you
remove the more the handicap. In some cases the stronger player may need to take out more than one piece.
 
About supporting handicap games i.e. arimaa here is article from github
 
Hope this information will be helpful for you. Besides, I would be grateful if you will visit my website

At this rate, there could be a challenge to create a game, let AI play itself, and then defeat the AI at the game.

 
Such a game can't be created, an AI that plays itself means it has genetically developed to know how to respond to all moves made (AlphaZero evaluates 80K moves per second - https://www.chess.com/forum/view/general/alpha-zero-stockfish-number-of- moves-per-second-vs-hardware-debate). The only way to beat it would be to either start the game with a forced win for the player, or make the game have some luck factor in it.

 9   Arimaa / Bot Development / Re: Sharp 2015 available for download  May 20th, 2018, 10:57am 
Started by lightvector | Last post by elescondite
That's pretty cool, lightvector.  I downloaded it, though I haven't tried running it yet.
 
My bot (bot_eliminator) is continuing to teach itself the game.  It's a very slow process, though I have been encouraged by recent improvements it has made.  You can see it in its rating, which is gradually improving after remaining flat for quite a while.  I've actually begun working on an improvement to the learning process, but implementing it is going to take quite a bit of time.  If only I could make AI research my full-time day job…
 
Your bot has provided the standard to beat.  Nice work developing Sharp.  My goal continues to be to create a self-taught bot that is competitive with Sharp, and hopefully can beat it someday.  Maybe we can resume the computer championship matches at some point when there is realistic competition available.
 
Until then, congratulations on being the developer of the most powerful Arimaa player in the world.

 10   Arimaa / Events / 2015 prediction contest prizes  May 17th, 2018, 1:23pm 
Started by SilverMitt | Last post by SilverMitt
Hi!
 
I don't think the 2015 prediction contest prizes were ever paid out (at least not in my case).  I would like to get that resolved before I run out of Arimaa points.  Thanks!
