Sting-sf-8

[carldaman]

The new version of this project is a next step in my searching for a quasi-intelligent chess engine.

I don't know if you may see the correct solution of each difficult position, but I hope you are much closer to get it now.

Sting-sf-8 is still based on an old version of Stockfish-211.

Nice, thank you.
When you say "quasi-intelligent", means that you encoded in it is some sort of learning capability?

I see that many of you still like my idea.

Sting learns only by my deep understanding of possible problems with difficult positions for standard engines.

BTW.
Note that now Sting starts with THREADS = 1.

Hi Marek,

you wrote last summer (July 18th) here:

> It is probably the last version based on old Stockfish 2.1.1. I will try to move my ideas to the newer 3.0 version. [/url]

Will this lead to an advantage over version 2.1.1 at all?

Is it not better right away go to SF5 or SF6 ?

But I guess the code of SF5 / 6 is completely different, so the transfer of your ideas is now technically not possible without starting from the beginning.
No matter, thanks for your Work on Sting and the constant improvement!

SF3 is not a great version of SF. It dates back to a time just before the testing framework really took off, and significant improvements came after it.
I agree that SF6 would be a much better choice, but it's up to Marek - we appreciate his efforts.

Sting is a tough project and needs much more time than I am able to sacrifice to do it in a perfect way.
Of course it would be good to move my project to a higher version of Stockfish and to see what it gives now.
Indeed, I have thought about the version of Stockfish 3 first.

At this moment, you can try to solve each difficult position. But it doesn't mean that I recommend you to bay a much better computer to check it.

Thank you Marek !

Hi Marek,

on my System i7-6700 - 4 cores 8 threads, Win 7 x64, Sting shows during creating a Uci-Engine >Threads=8<

When i start Sting now, it shows in ChessBase 14 >4 CPU< and around 9500 kN/s.
Change it to 1 CPU it shows still 9500 kN/s - Task Manager shows 61% ! CPU-Utilization.

When i set >Threads=1< in Uci-File and starts Sting now, it shows >5 CPU< 2500 kN/s and 12% ! CPU-Utilization.
Increase to 4 or 8 Threads in CB-GUI shows still 2500 kN/s and 12% ! CPU-Utilization.

All other Engines have not this behavior.

Herbert, I can't understend you. Sting Sf 8 should start with THREADS = 1. I don't use Chessbase and I can't help you.

[Dann Corbit]

The thread count and NPS seem to work fine with Arena.
I only tested it there.

Hi Herbert!

All I see in chessbase 12 is that the n/s don't gain so much over 50% CUP- usage as for hyperthreading on, and not much more than 80% is reached in Windows Taskmananger, which was normal for SF 2 as far as I remember. Tried an semi- old Intel X5650 Xeon with 12x2,67GHz.
Yet % of CPU- usage in TM, threads-count and n/s correlate reasonably here for me too

[lech]

Hi Marek,

on my System i7-6700 - 4 cores 8 threads, Win 7 x64, Sting shows during creating a Uci-Engine >Threads=8<

When i start Sting now, it shows in ChessBase 14 >4 CPU< and around 9500 kN/s.
Change it to 1 CPU it shows still 9500 kN/s - Task Manager shows 61% ! CPU-Utilization.

When i set >Threads=1< in Uci-File and starts Sting now, it shows >5 CPU< 2500 kN/s and 12% ! CPU-Utilization.
Increase to 4 or 8 Threads in CB-GUI shows still 2500 kN/s and 12% ! CPU-Utilization.

All other Engines have not this behavior.

Herbert, I can't understend you. Sting Sf 8 should start with THREADS = 1. I don't use Chessbase and I can't help you.

Indeed it can be my bug. I willl return to the old Stockfish 2.1.1 start THERADS = max. possible threads.
Please don't use Sting SF 8 and wait for version 8.1 soon.

[Vinvin]

I willl return to the old Stockfish 2.1.1 start THERADS = max. possible threads.

May be half the max because of all the hyperthreaded CPUs now.
