Stockfish time management is BADLY broken

[Damir]

Let's hope Stockfish not start losing on time, like in the previous TCEC, 2-3 seasons back.. Stockfish time menagement must be fixed.
I am am quite surprised that this problem has not been fixed by now.
Also when testing Stockfish in Fritz GUI, both offline and online, Stockfish is losing many games on time.
It is not just LittleBlitzer, but other GUI's as well that Stockfish is losing games on time.

Let's hope Stockfish not start losing on time, like in the previous TCEC, 2-3 seasons back.. Stockfish time menagement must be fixed.

It will probably survive in games with a fixed increment per move.

But after a more in depth look at the code, I can only conclude it is totally broken at time controls like 60 moves per 2 hours. For example, at move 52 it might use all of the remaining time except for 100ms Move Overhead. It will then try not to touch that remaining 100ms in the last 8 moves before the increment. So if it does not get flagged, it will blunder anyway.

I am am quite surprised that this problem has not been fixed by now.

Evidently this has not been properly reviewed and tested before it was committed.

I tried to play 22.9.2017 version with 60 moves in minute level. I must stop, when 15% of games were lost by time against Houdini.

This game was draw already 10 moves before time control (I have syzygy installed and cached to RAM) .

It is broken, in longer games (15 + 15 seconds ) it leaves very little time after only 40 moves. They test it at super fast time controls - but things like time management , which was fine before should not have been touched. But with that said, there are a LOT more positives with how Stockfish is updated and improved and I'm sure they will get around to fixing this at some point in the future. Once they realize they have a problem, right now they are clueless there is a problem, but at some point it will pop up in TCEC 10 and then they will fix it. It's broken in SF-McBrain too. I meant to keep that patch out - but I forgot. I have to take look and see if I revert easily - not all patches can be reverted easily once other patches are over laid on top of the initial patch. Then it's very easy to cause even more damage. They made a lot of patches in the last two months that were not really Elo related, but changed a lot of lines of code.

[hgm]

Actually partial reason for time losses can be just LittleBlitzer! It starts game always with move 1. even if there is 10 move pgn opening - no good.

It should not matter at all how the GUI mangles the time control, as long as it does it consistently. The GUI is both in charge of telleing the engine how much time it has, and of deciding whether the engine overstepped this time. So no matter how deluded it might be about whet TC the user wants, it should never give rise to any forfeits if it just enforces what it told the engine.

[Jouni]

Engine should NEVER lose on time with X/Y time control when CPU can execute one instruction in nanoseconds . Fix before SF9 please.

[stavros]

i played a game vs latest sf dv at 40 moves in 3 mins/40 moves in 3 moves
i didnt see any bad time management from st ,it used perfectly its time
also i didnt see any lack of time the last 5-10 moves
at what time contol st has this problem?
GUI fritz 12.

[Modern Times]

One game ? Play more.

[stavros]

i played me vs st 2nd game again st, no time problems
i wonder...what % of the games this problem appears

[corres]

If you like old time manager of Stockfish you can return it an easy way:

1. Copy from the Stockfish source before Aug 17 into the newer source
the next three files:
- timeman.cpp
- timeman.h
- ucioption.cpp
and overwrite.

2. In the ucioption.cpp modify the next line:
void on_threads(const Option&) { Threads.read_uci_options(); }
as the follows:
void on_threads(const Option& o) { Threads.set(o); }

3. Compile the source.

That is all.

[syzygy]

I guess I should have used Stockfish, but a match at 60/60 between Cfish and Cfish (with time management identical to that of Stockfish) results in at least 10% time losses (cutechess-cli, default Move Overhead):
