Is this prize still on? Because for this amount, it sounds definitely doable.
 
Since AlphaGo Zero, several improvements to the network architecture and learning process have been invented. Just by applying what has been done in KataGo for Go should probably be enough.

Hello Everyone!
 
I discovered Arimaa around 10 years ago. Crushed some bots, got crushed by kzb52.
 
I have Jean Daligault's book on my shelf. Smiley
Although I don't have time to play Arimaa, being much more invested in Go, I have always been fond of it in the back of my head.
 
It is certainly an underappreciated game and an interesting open frontier for better bots.

Here's an interesting paper: Benjamin G. Rin and Atze Schipper out of the University of Utrecht have proven that Arimaa is PSPACE-Hard:

At the end of the paper, the authors say that they expect someone eventually to show that arimaa is EXPTIME-Hard.

 7   Arimaa / Events / 2024 WC Rules, Format, and Schedule  May 18th, 2024, 9:15am

Hi.  The WC event may perhaps be created soon.  Omar seems to be happy to go with something a lot like last year, which was triple elimination, although it might be good to discuss the time control, where the 6-minute maximum move time was turned on, but still with the high reserve to start.
 
Also it might be good to figure out exactly which pairing algorithm to use, as I believe I was not aware of subtle differences last year for the triple elims.

As a very belated historical note, the chosen values for the constants of HarLog, Q and G, are effectively fully determined by:
  • (as mentioned) being indifferent to an initial trade of a dog for 2 rabbits and
  • having the advantage of an initial trade of a horse and cat for a camel be exactly flipped after all the dogs come off the board.
This works out to finding the positive value Q that satisfies:
G = (Q^2 + 13*Q + 38)/((Q^3 + 15*Q^2 + 74*Q + 120)*ln(10/7)) = -2*(Q^3 + 5*Q^2 - 2*Q - 22)/((Q^4 + 11*Q^3 + 41*Q^2 + 61*Q + 30)*ln(65/56))

It had to do with a network setting, indeed. Thanks for the hint; I can play again!
