Re: Estimated Elo Perfect Play

I have different interpretation of draw reasons and have methodics how to verify it or neglect. Draw rate of 2500 engine A vs 2500 engine B might be low, because they have different strength and different weaknesses (it's like in thriathlon 2 athletes got the same time on finish, but one is very bad...

Re: Maybe an reaction to contempt from the Komodo team!

Means engine should have an own contempt configuration table and can switched automatically to a higher or lesser contempt factor.
For SF to implement anything - it must pass Fishtest.

So you have to modify Fishtest to play not only self-test, but also vs 3rd party

Re: benchmark new smartphones:

Is there any way of knowing what version you get before buying. I live in New Zealand and would hate to buy the S7 only to find out later that it is the Snapdragon version. The Samsung NZ site does not state what specs are for the CPU but list all other specs. Can't you ask seller before purchase? ...

Re: Animation : Ratings of go players since 1974 !

Why are those ELO numbers so high in comparison to chess? Do they add a flat +1000 or something? :) Drawrate (thanks to opening knowledge and possibility of drawish tactics: exchanges, repetitions, agreements) hold ELO distribution so tight. For chess engine to be 3400 against human - mean no singl...

Re: benchmark new smartphones:

Huawei Kirin 920 = ARM big.LITTLE: 4 cores Cortex-A15 + 4 cores Cortex-A7 It depends if big + LITTLE cores can be run simultaneously. Exynos 5410 can run either 4-A7 either 4-A15 cores Exynos 5420 can run both 4-A7...

Re: Search for mate not found the "best" sequence.

Playing by DTZ would go for the fastest Pawn push or capture. (Unfortunately also if it is the opponant that makes that capture, leading to a quick sacrificeof all the material not absolutely needed to win.) So if you derive the evaluation by adding a constant to the probed DTx of an EGT, the delay...
