Testing LazySMP

[Sylwy]

I've released LazySMP 6.0 which is probably more powerful than the previous version.

Hi Silivan! In my experience, the even versions are not good at all:

Code: Select all

LazySMP 2.0, LazySMP 4.0, LazySMP 6.0, ...

I suggest you download version 7.0:

OK. It entered in my tournament replacing v.6.

The problem is v5 waits forever instead of playing, if ponder is on and the checkmate is about to happen.
If you compare the last move from LazySMP from both log files:
1) Ponder off

Depth 127 is reached after less than one second thinking time (13:30,890 to 13:31,609 = 719ms) and score is 124.02
Qh8# is played 16ms after that.

Depth 127 is reached after less than one second thinking time (10:50,801 to 10:51,513 = 712ms) and score is 124.02
This is definitely consistent with the thinking time used in the above ponder off test.
Opponent's move (Kh6) fits the pondering expectation and is played at 10:51,779 but nothing happens until the GUI sends the --> stop command, interrupting the "thought" process. It is a user-forced stop.
The engine didn't play from 10:51,779 to 11:45,580 thus 53.801ms. That's already 75 times the used delay to calculate the solution, and actually is unlimited (only stopped upon user request).
Once forced, the engine then immediately answers (<--) the prepared move that was pending. But of course in a serious match that would be a loss on time instead of a win, as nobody would manually trigger the awaited move.

Thanks... but I see no point to solve this problem because this problem only exists in version 5.
Please let me know if you could find such a problem in v6.0 or v7.0, then I solve it.

[Tibono]

or much better... perform the required testing yourself? I shall not test this engine any further.

[LazySMP]

I found such a problem in v7.0. I solve this problem ASAP!

You helped me a lot. Would you like to add your name to id author section in new LazySMP version?

[LazySMP]

Thanks again to the CCRL members for testing my engine.

Due to the fact that LazySMP 3.0 was the fastest version of the engine, increasing engine power has no effect on increasing the Elo rating on Blitz matches.

I think LazySMP 7.0 is waeker than LazySMP 5.0 and LazySMP 5.0 is weaker than LazySMP 3.0. So I would like to ask Graham if it is possible to test my engine on CCRL 40/15?

[LazySMP]

I've released LazySMP 7.1 which is probably more stable than the previous version.

Changes of 7.1 compared to 7.0:

• Fix ponder bug on max ply

I would like to thank Tibono for finding this important bug, and I've added his name to the list of engine authors as a token of appreciation.

Code: Select all

uci
id name LazySMP Version 7.1
id author Daniel Pierce, Silvian Rucsandescu, Eric Bonneau
option name Threads type spin default 1 min 1 max 64

Looks to work fine, thanks!

Not at present. Perhaps when you reach the 2400 level.

In the meantime I am still working my way through a long list of engines that are stronger and have been waiting to be tested.
Just a note that the authors of these engines aren't continually pestering me and I appreciate their patience.

Please look at this chart. As you can see, the engine speed is decreasing, so I don't think it can reach 2400 rating at least in fast games.
If you can test my engine outside the queue, I promise to raise the engine rating to 2400.
