RAPIDROID RELOADED: March-2016 featuring Fritz 14, Gull 3 & Ivanhoe 9.47c

Following plenty of gauntlets, here's another update with some strong newcomers that we've been waiting since a long time.

Despite the high hopes, Fritz and Gull were not able to break into the top 5. Stockfish 7 still crushes everything that gets on its way. Fritz and Gull could bite Komodo from time to time but they can't steal enough draws from Stockfish. That makes the gap between the fish and the reptile more visible now. Android needs a new Komodo version...

The highlights of this release:
* ADDED Fritz 14
* UPDATED Gull 1.2 to 3
* UPDATED Ivanhoe 9.46h to 9.47c beta
* DELETED Cylcone due to similarity with Grapefuit & Toga
* DELETED The Mad Prune due to similarity with Grapefuit & Toga

After 4 extra days of delay, i was able to finish another complete round and to increase the number of games by 18, so that this release is not only an introduction of updates but also some more games by all engines. Narrower error margins matter, though, it's still more than 30 ELOs.

The nasty rule is: Less error requires more games >> More games require more full rounds >> More full rounds require less gauntlets, less updates. Unfortunately, the latter happens very rarely.

One thing which gets clear is the relationship between the average ELO difference between players and the accuracy of the ranking.

Shortly said, the main targets of a perfect rating list are:
* Unlimited & equal number of games played by each engine
* 100% draw rate
* Average ELO difference between opponents of each game = 0
* For each engine, a perfect bell curve distribution of the number of games vs all opponents within the neighborhood of +/- 100 ELO

Sure, no list can reach above targets at once. One can get close to the last one with extreme care but the first three are utopic and impossible.

No matter what, in order to improve the quality of Rapidroid, i've recently decided to continue with less promotions between divisions. It used to move 3 engines up and 3 engines down out of 10 engines after each round.

As it often leads to pairings beyond 200 ELO gap, 2 up and 2 down should be better.

Now, i expect that the draw ratio will increase. The average ELO gap must decrease in parallel. At present, Rapidroid has a low 25.7% draw ratio and ~100 ELO average gap which both mean the overall pairing scenario has been too agressive.

Targets for next release:
* UPDATE Arasan 18.2 to 18.3
* UPDATE Rodent 1.7 to II
* UPDATE Tucano 5.0 to 6.00

Have a nice checkmate!

  1. Hi Gurcan!
    Do you know how to add opening book to SF 7 in C4a?

    1. Alex, no. It doesn't work. Only Komodo and a few others which come with indirect methods like Critter.

  2. Hello Gurcan,

    Indeed, we need next release Komodo or "new" reptile/fish in rating list ;-)

    Good job! Thank you :-)

  3. What program do you use to calculate/record your Bayes Ratings? Is it a program or spreadsheet that you can publish a link for on here? Thanks.

    ReplyDelete
  4. I maintain all the rounds in a huge excel file where all openings, promotions and updates are monitored. Is this what you wanna see? Other than xls, there's nothing specific: Some Arena help to verify, one big pgn per round and bayeselo to calculate

  5. Thanks for the information. I've been manually entering and keeping tournaments and gauntlets on a spreadsheet too and manually calculating the elo, but wanted something more automatic. I found both the Bayes program and ELOstat that pulls all the data straight off the tour.pgn file that CfA creates. Really liking ELOstat as it is VERY easy to use. Thanks again.
