hi swami,

Could you give us (a) formula(e) of an approx. rating of
the engine, based on the corresponding sts results?

best to you,

Hi Harun, I believe it's definitely over 2100 as per the CCRL. Could be around 2150 - 2250. Since it scored really high on Re-Capturing and Bishop vs Knight.

One thing is for certain, it's a balanced/positional engine. Not an aggressive/attacking one. (since it doesn't favor Open files/Square Vacancy)

How does Lime 66 (2278 CCRL) compare scorewise?

Cheers,

Hi Graham, I haven't tested Lime 66 yet, It was released nearly 1.5 years ago. Long before the first version of STS I believe

I'll test it and post the results later tonight, for comparison purposes.

Thanks Swami.

I had Jabba about 100 points less than Lime in my testing.... I use Lime 66 as part of my "fixed testing group"

[Richard Allbert]

For comparison I had

Code: Select all

STS1	51
STS2	35
STS3	46
STS4	40
STS5	63
STS6	56
STS7	37
STS8	28

You can run the tests with Jabba alone, my batchfile as an example...

Code: Select all

jabba10 -epd -i STS1.epd -o STS1.txt -t 10 -ini jabba.ini
jabba10 -epd -i STS2.epd -o STS2.txt -t 10 -ini jabba.ini
jabba10 -epd -i STS3.epd -o STS3.txt -t 10 -ini jabba.ini


..etc

This runs jabba10.exe -i is the inputfile -o the results output file, -ini the ini file (although it doesn't need this, looks for jabba.ini if not specified). -t is the time limit in seconds, -d would specify depth

Ok. around 2100-2200.

What I meant was something generalized:

You might roughly predict an engines rating:

Approx. Engine Rtng = a0 + a1 * sts1 + a2 * sts2 + ... + a8 * sts8

if a0 ... a8 known beforehand.

Something like that. Useful when determining start ratings.

That sounds good. No, I don't have that kind of formula, I just compare scores with other engines that scored similar.

If anybody else has some kind of formula for calculating such, let me know!
