March Madness

[tsmiller1]

Nice idea, but why are you using older versions?

I made a deliberate decision to test the engines that have been rated by the CCRL organization (plus one of the Ippolit family). I used the latest list I had access to (04/09/10). Obviously, the latest versions of engines will take a little time to make the CCRL list as they are tested. I don't want to start chasing the latest version of every engine, because that could be a never-ending pursuit, plus, the latest versions are not always the highest rated (per CCRL).

However, after I'm finished with this tournament (it'll probably take me 1.5 to 2 months), I may do the whole thing all over again using the engines from the latest and greatest CCRL list.

The Ippolit engine was a bit of an issue, because they are not rated by CCRL, so I did a 300-game G/5 round robin of the 5 members of the Ippolit family of which I could find the latest versions: Ippolit, Robbolito, Firebird, Igorrit, and IvanHoe. Ippolit 0.080b3 won this tourney with 69.0/120.0, so I chose it to represent the Ippolit family. Maybe not the most rigorous way to do things, but this is just my fun thing I'm doing.

This doesn't seem to be the case. The list has Arasan 10.0 with a rank but Arasan 11.7 is above it in the list in terms of rating - and 11.7 is indeed almost certainly stronger than 10.0

You'll notice that Arasan 11.7 is listed in non-bold type. That means that they haven't tested it with enough games to give it on official CCRL rating, but they listed it so people would be aware that the testing is underway, and the higher rating may (or may not) hold up. Maybe too much information, but I think once you work with it a while it is very good way to present the list.

OK, Round 1 in Bracket A continues with No.2 seed Thinker defeating No. 15 seed Philou 4.5-0.5. Spunky little Philou drew the first game, then it was all Thinker the rest of the way. For an engine that doesn't show it's thinking, Thinker thinks pretty darn well, apparently.

No. 3 seed Bright put a hurtin' on No. 14 seed Little Goliath Evolution, winning easily 5-0.

Next up: No.4 seed Bison vs. No. 13 seed GarboChess!

[tsmiller1]

No. 4 seed Bison made quick work of No. 13 seed GarboChess, winning 5-1.

I'm having a heck of a time finding either Crafty 23.1 or Tornado 2.2. If some kind soul can point me in the right direction to get these two engines, I will be appreciative.

Thanks.

Until I can find Crafty 23.1 and Tornado 2.2, I'm going to complete the rest of the Bracket A. No. 6 seed Alaric faced No. 11 seed Amyan. This was a tough battle for a while, but Alaric pulled ahead to win 4.5-2.5.

Next up: No. 7 seed Collosus vs. No. 10 seed Deuterium.

Sorry - just saw this. I'll put them in CCRL public for you shortly.

Cheers,
