 2   Arimaa / Bot Development / Re: (no) absolute score values for pieces?  Nov 18th, 2023, 9:13am 
Started by clauchau | Last post by aaaa
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!

You can go to the "Navigation" Bar on the left of the gameroom, then select Games -> My Recent Games. On there, just click on the gameboard icon for the game you want to look at.

This hasn't been mentioned on this forum yet, but a relatively recent YouTube video already has by far the most views of any about Arimaa: https://www.youtube.com/watch?v=-l028j_eqZE

Regarding color assignment:
 
I'm leaning towards preferring the priority of these two rules to be swapped, because there's only a limited opportunity for the pairwise color balance to be equalized (and history has certainly not shown there to be a significant enough advantage of one side over the other to justify giving priority to global color balance).
 
Especially with that in mind, I also don't see the point of having a separate set of color assignment rules for 2 and 3 Players.

 
I tend to agree with you on this. Although in Arimaa the color does not seem to matter nearly as much as in Chess.

 10   Arimaa / General Discussion / Re: Arimaa Variants at Boardspace.net  Apr 20th, 2023, 7:00am 
Started by ddyer | Last post by clyring
Intuitively I'd expect the small variant to usually reach a "traffic jam" state pretty quickly. There is only one trap, so each player's elephant can permanently shut down the other player's capture threats by waiting next to it. After that, it is likely very hard for either to make progress.
 
The wider board could be interesting. Pieces fighting for the wider flanks are somewhat removed from the trap control fight, and this has both positives and negatives. (A piece hiding in the corner is already often difficult to chase down on a normal board.) I might give it a try this weekend.
