New builds, based on PA_J + GTB, attached. github updated.
Testing so far seems good. I chucked the tournament I was running in favor of a very fast tournament when I discovered an issue with the opening books (I was using Stockfish's own book for all 3 engines. Apparently Stockfish only knows how to play the Najdorf.). I guess that this is why I don't generally run tests -- too dumb. Stockfish_64 and Stockfish_PA_I_GTB_64 were neck in neck, with PA_J_64 about 6 games behind. With a round-robin tourney of 75 games, that could mean anything.
In general, very drawish play between these 3 engines, which is to be expected. I don't think the modifications have much, if any effect on strength, time management, etc. whatsoever, at least not at these time controls.
BTW, I increased the number of cores on my VM to 2, so we're seeing multicore runs here.
New tourney. 5 seconds + 100ms, 300 games total which makes for a better sample size. I suspect that the PA_J is a tiny bit weaker than PA_I based on what I was seeing in the 1/1 games, but let's see how it fares at these time controls.

Re: Designing an analysis friendly Stockfish?
In case anyone else wants to run some tests, here are the 3 engines I'm working with, all compiled with exactly the same settings.

Re: Designing an analysis friendly Stockfish?
Any results with the longer time control game for this fix? These updates to history/killers are in version I. Against the default with the new ok_to_use_tt() SF I have a score of +235 -140 =156 from the perspective of the default version at g/24"fruity wrote:The change regarding history and killer moves seems to work well only at lower depths. I'm actually running a 1000 games 20 sec. match, 6 Threads. SF default is clearly in front after 800 games. I'll test SF PA_G against SF default at longer tc tonight.Uly wrote:Thanks fruity and gaard, here's a quick comparison of Stockfish PA_G and PA_H at 1CPU in the opening position. It seemed mostly luck, but PA_H found 1...e6 much earlier and reached depth 24 much faster, PA_G caught up at depth 25 and finished one minute faster in the end, though.

Re: Designing an analysis friendly Stockfish?
I would imagine that fast time controls would amplify any slowdown due to additional tablebase or hashing activity. In which case, all seems well. I'm running a 450 game round-robin at 5 minutes per game. I'll post about that tomorrow.

Bozo the Clown at RF suggested to make a new compile of Stockfish Default and use it for the testing, instead of JA's compile, to compare apples to apples (speed of the compile would be a non factor, clear improvements would stand as better code.)
Good idea. These are all compiled under the same conditions and are the most promising versions, IMO.

Re: Designing an analysis friendly Stockfish?
I'm still fiddling around. According to my tests at 20'' all the versions so far are 10-15 Elo below SF default. Best result I've found so far isgaard wrote: Any results with the longer time control game for this fix? These updates to history/killers are in version I. Against the default with the new ok_to_use_tt() SF I have a score of +235 -140 =156 from the perspective of the default version at g/24"
(1) remove the history/killer tweak. It seems to work well only for low depths. Could be reintroduced later with tweaking for low depths only, but at the moment it doesn't help to find the best PV TT code, so leave it away for now.
(2) use template and inline for ok_to_use_TT() and the following code
Code: Select all
template <NodeType PvNode>
inline bool ok_to_use_TT(const TTEntry* tte, Depth depth, Value alpha, Value beta, int ply) {
Value v = value_from_tt(tte->value(), ply);
return
PvNode ? tte->depth() >= depth && tte->type() == VALUE_TYPE_EXACT && v < beta && v > alpha
: ( tte->depth() >= depth
|| v >= Max(value_mate_in(PLY_MAX), beta)
|| v <= Min(value_mated_in(PLY_MAX), alpha)
)
&&
(
((tte->type() & VALUE_TYPE_LOWER) && v >= beta)
|| ((tte->type() & VALUE_TYPE_UPPER) && v <= alpha)
);
}
It seems there is still work left to find a real neat solution regarding the playing strength.

Re: Designing an analysis friendly Stockfish?
I'd guess it's probably a bug in the GTB probing. Is the Decemberists' patch applied?Jeremy Bernstein wrote:Here's a game:
...
Note how the PA_J+GTB finds a forced mate around move 80 or so and then loses its way by move 99. What happened?
I added a UCI option to control the depth in ply it's used up to. With my default setting of 20 (which could/should be tweaked a bit), it's tad better than SF default at 40 moves/1 second.fruity wrote:(1) remove the history/killer tweak.

I've noticed that our SF tends to lose on time more often than the default at hyperbullet (40 moves/1 second), especially in the first 4-5 games. Has anyone else noticed this behavior?
