Fairy-Stockfish janggi (ponder Problem)

[janggi-korea]

NO !, Hash can never give up. It has to do with strength. One of our goals is playing strength. Currently we can use the hash even if we run the new game. It couldn't be used before.
Previously, the hash was cleared after a new game.

As of now, I can use the hash even if I run it again after exiting Winboard. Right?

[H.G.Muller]

Not unless you mean something completely different with 'hash' than its usual meaning. When one talks about 'hash table' in a chess engine this usually refers to the 'Transposition Table', a large chunk of working memory used by the engine to shortly remember positions in the search tree it has already evaluated, but which might be reached again in the same tree by playing the same moves in another order, or moving a piece to the same destination through a different path. As this is in working memory, and not in a file on disk, the info will always be completely gone as soon as the program terminates.

If you refer to some other feature of Stockfish of which I am unaware (which is very possible, because I hardly know anything about Stockfish), which stores information on disk in a file, then it is of course possible for any instance of Stockfish started later to use that same information. That would then of course also apply when restarting Stockfish for a new game. A restart is a restart, and if Stockfish is programmed to load some file with useful information at startup, it will do that.

I have never seen such a file in the SF directory, though.

[janggi-korea]

Well, when I tested it, I can definitely use the hash if I don't restart the winboard.
However, I'm not sure if I can use the hash if I restart after winboard shutdown. I thought it was possible.
Perhaps you are right. Because I am not familiar with FS code.

[H.G.Muller]

What do you mean by 'using the hash'?

As I said, engines use hash tables for speeding up the search, preventing they would have to search the same position multiple times. But even with today's memory sizes, the number of positions they search per second is so large that the table will be completely filled in a minute or so. After that anything they want to add must push some other position out of the table. To minimize the negative impact of that they preferably throw out positions which are no longer occurring in the search tree. After some pieces are traded, positions that still have those pieces on the board will never occur anymore, and are then flushed out of the table for storing positions that are relevant. At the end of the game there are no positions left in the table that would occur in a search of an opening position, which still nearly has all pieces.

So keeping the info in the table from one game to the next is completely pointless. Unless there were no pieces captured at all in the previous game.

Some engines have what they call "persistent hash", which is a file where info on positions that have been searched very thoroughly can be stored. This is a feature that can be useful in interactive analysis, where correspondence players sometimes spend days on analyzing one particular position to see what they should move. They can then switch off the computer, and continue later with the same position. But this is not more useful for increasing general playing strength as an opening book; it is in fact very similar; you could in theory make an opening book by making an engine searching the initial position, and storing its search tree.

Usually engines that support persistent hash then have an option where you can specify the name of that file. (So that you can use separate files for analyszing different positions.) I see no such option in Fairy-Stockfish.

BTW, I could not find anything suspect in the 'new' command. It doesn't refer to ponderMove at all, so it should make no difference whether that is cleared or not. This worries me a bit: it seems that the starting and stopping of ponder searches somehow leaves Stockfish in a corrupted state. And there is no knowing whether the corruption would affect the quality of the moves. I always dislike it when things happen for which I have no explanation.

[janggi-korea]

OK got it. Thank you. Now I understand clearly about hash. I fixed the bug by adding your code. I will give up the hash.
Now we can fix the openingbook problem again.

ps. How much hash memory size in Winboard's for Best strength? Also, make sure the core and thread settings?
I use 16 ram 4 cores 8 threads.
I will upgrade my computer to do research with more accurately.

[H.G.Muller]

It depends entirely on your hardware, and how many copies of Stockfish you run simultaneously. It is in general unwise to use more than half your computer's memory for the total of all hash tables of all engines. Also note that the search speed (and thus playing strength) is only very weakly dependent on hash size; to double the speed (and gain some 50 Elo, typically), you need about 4000 times larger hash. And increasing hash size is not completely free even if you have the memory, because the CPU uses caches for the memory mapping, which start to overflow if too much memory is used in quick succession (which a hash table typically does). Which makes the individual memory accesses slower. Personally I always use 256MB for my engines, but I guess that by today's standard's that is much smaller than needed. But who cares about 5 or 10 Elo more or less; those are basically unmeasurably small differences, that you can only detect after tens of thousands of games.

As for the threads it depends on how many cores your CPU has. Nowadays all CPUs use 'hyper-threading', which doubles the number of 'virtual cores' compared to the number of 'physical cores'. So if you have a quad-core CPU, Windows will indicate 8 cores. Some people say you should not use more threads as you have physical cores, so that all cores can work at maximum speed. But others claim that letting one core do the work of 2 does make Stockfish a little bit stronger, and say you should use as many threads as you have virtual cores, minus 1. (The latter to keep some processing power for other tasks; making the engine very fast is not helpful if that leaves no computing power for entering moves.)

BTW, from discussions at GitHub I got the impression that the SF Janggi implementation is weak because of poor evaluation. This usually cannot be solved by speeding up the search. Actually it can backfire. The better you search, the more likely it becomes that the engine finds a clever way to realize a counter-productive goal, where it mis-evaluates it as being good, while in fact it is very bad (like keeping Cannons in the end-game rather than Pawns). Search (i.e. speed) is not the answer to that.

[janggi-korea]

Okay. I understood correctly. Thanks.

I found 3 bug.

1. In three variations, if i double-click the "King", the "King" disappears, and the king can be moved in place regardless of the Test Legality check. (/variant=janggi is normal.)
/variant=janggimodern
/variant=janggicasual
/variant=janggitraditional

2. When I use "move now/Retract Move" the highlight dragging disappears and I can't move the piece. If I do movement by dragging with the mouse,(Forced movement) the game stop and the engine continue to run ponder.

3. Engine vs. Human When playing, sometimes the engine does not move and only pondering. And when I use the "edit game", the engine does not search for itself, it searches for my play movement.
I copied the FEN and started the game again. And the engine searched itself again normally.
Please check and solve it.

** Engine- "Hint / book" If i Use the menu the ponder stops. And I can't use Hint and Book.
But after that, i can start game and ponder normally again with one move.
I think this is probably because the stockfish engine doesn't support it. right?

[H.G.Muller]

1. In three variations, if i double-click the "King", the "King" disappears, and the king can be moved in place regardless of the Test Legality check.

I see. It appears that Stockfish internally encodes turn passes as a non-move of the King, so that the King itself gets highlighted when you select it. Such highlighting can be suppressed by changing (in xboard.cpp) the line

Code: Select all

              if (is_ok(from) && UCI::square(pos, from) == token)

to

Code: Select all

              if (is_ok(from) && UCI::square(pos, from) == token && from != to)

2. When I use "move now/Retract Move" the highlight dragging disappears and I can't move the piece. If I do movement by dragging with the mouse,(Forced movement) the game stop and the engine continue to run ponder.

The 'retract move' works through a CECP command "remove", and Stockfish apparently does not support that. You can add support for this by adding (in xboard.cpp, e.g. just before the comment "// Bughouse commands":

Code: Select all

  else if (token == "remove")
  {
      if (moveList.size() > 1)
      {
          if (pondeMove != "")
          {
              Threads.stop = true;
              Threads.main()->wait_for_search_finished();
              undo_move(pos, moveList, states); // take back ponder move
          }
          undo_move(pos, moveList, states);
          undo_move(pos, moveList, states);
      }
  }


3. Engine vs. Human When playing, sometimes the engine does not move and only pondering. And when I use the "edit game", the engine does not search for itself, it searches for my play movement.
I copied the FEN and started the game again. And the engine searched itself again normally.
Please check and solve it.

Hmm, this sounds like a bad problem. The engine is not supposed to search at all in 'Edit Game' mode. What you describe sounds like a failure to terminate the ponder search by a move that you entered. I cannot imagine now why that would happen. Can you make a debug log of a situation where it happens? If it is long, just post the last 2 or 3 searches of the log here.

** Engine- "Hint / book" If i Use the menu the ponder stops. And I can't use Hint and Book.
But after that, i can start game and ponder normally again with one move.
I think this is probably because the stockfish engine doesn't support it. right?

Hint and Book also use commands not supported by SF. 'Book' is for requesting the content of Stockfish' own opening book, but it does not have one. But it seems it would be best to recognize these commands (and perhaps a few others) as commands that should be ignored without disturbing the ponder search, even if they are meaningless to SF. (And Hint could simply print the ponder move, even when pondering is off.)

I will think of a patch to do this. For now, just don't use the commands.

[janggi-korea]

1. Solved. thank you.

2-1. Retract Move: Solved.
2-2. move now: still I can't use highlight dragging after the engine moves. And the engine keeps pondering, ignoring any commands.(e.g edit game)

3. keeping ponder... and The engine stops when using the "edit game" mode. And I had to run the engine again. (machine WHITE/B). After that, the engine analyzed my movements.and engine does not move. Occurs very occasionally. I will make a debug file to make sure it is correct.
(Not sure currently. I'll check exactly.)


else if (token == "remove")
{
if (moveList.size() > 1)
{
if (ponderMove != "")
{
Threads.stop = true;
Threads.main()->wait_for_search_finished();
undo_move(pos, moveList, states); // take back ponder move
}
undo_move(pos, moveList, states);
undo_move(pos, moveList, states);
}
}
// Bughouse commands
else if (token == "partner")
Partner.parse_partner(is);
else if (token == "ptell")
{

[H.G.Muller]

'Move now' also works through a CECP command ('?') that Stockfish apparently does not implement.

I discovered a general flaw in the way Stockfish handles unknown commands in CECP; it handles those like they are moves, and when a move is illegal, it prints an 'Unknown command' error message, rather than 'Illegal move' even if it was a true move that happened to be illegal. Now that we added extra code in the move-processing part to handle pondering (to determine hit or miss) this flawed method has become even more undesirable, as unknown commands would be considered ponder misses.

To fix this, please replace the code (in xboard.cpp)

Code: Select all

  else
  {
      // process move string
      if (token == "usermove")
          is >> token;


by

Code: Select all

  else if (token == "usermove")
  {
      // process move string
      is >> token;


and the line

Code: Select all

          sync_cout << "Error (unknown command): " << token << sync_endl;


by

Code: Select all

          sync_cout << "Illegal move: " << token << sync_endl;


Finally, at the very end of the file, replace

Code: Select all

  }
}

} // namespace XBoard


by

Code: Select all

  } else
          sync_cout << "Error (unknown command): " << token << sync_endl;}

} // namespace XBoard


This should prevent unknown commands from aborting pondering. Illegal moves still would, but with legality testing on it should be impossible to enter legal moves. So at the moment I don't see a great need to fix that. (The solution would be to move the test whether the move was legal to before testing whether it is a ponder miss and aborting the ponder search. But this again would run into the problem that during pondering the wrong side is on move, so that any move would probably be considered illegal.)

If you do want 'move now' to work, you would have to add code to handle the '?' command, like:

Code: Select all

  else if (token == "?" && ponderMove == "" && !Options["UCI_AnalyseMode"])
{
          Threads.stop = true;
          Threads.main()->wait_for_search_finished();
}


e.g. before the "// Bughouse commands" comment again.

[janggi-korea]

Thanks, I will test more about the problem of "Ponder" stopping during the game.

2-2. move now: Not resolved yet. After the engine moves, I still can't use highlight dragging, and if I force move => engine ignores all commands and only Ponder.

[H.G.Muller]

I don't understand what happens here:

The ? command aborts the search, as intended, and the search thread prints a "feature GOTMOVE=1" as a result. So far so good. But then, after having processed the ? command, the input thread is supposed to wait until it gets a new command before doing anything. (In this case, wait for the "rejected GOTMOVE" response of the GUI, which would prompt it t send the move.) But instead it sends the move and starts a new ponder search immediately. Then, when the "rejected GOTMOVE" arrives, it tries to do that again, and this causes the trouble. It seems SF prceives a spurious input command after '?'.

To get a better idea of what is going on here, can you put an extra statement

Code: Select all

 sync_cout << "# command: '" << token << "'" << sync_endl;


directly after

Code: Select all

void StateMachine::process_command(Position& pos, std::string token, std::istringstream& is, StateListPtr& states) {


and then repeat this test, so we can see which mysterious command SF imagines that wrecks things.

[janggi-korea]

edit..

ok.. i see
I added a line like this.
void StateMachine::process_command(Position& pos, std::string token, std::istringstream& is, StateListPtr& states) {
sync_cout << "# command: '" << token << "'" << sync_endl;


I did upload 1028.exe/xboard.cpp to google drive.

for solution I suggest to you (simple).
How about stop the "ponder" for a while when using "now move"?
This is because the ponder works normally when not in use.

[H.G.Muller]

This is weird. After it received the '?' and stopping the search, it sends a move without passing the output command we just added. While the only place where it would print a move is ner the top of the routine, after that output command. There should be no way execution should be able to reach the code that prints the move from the point where it stopped the search without passing that print command. But it apparently does, as nothing gets printed.

Can you post the program code of the routine process_command we are using here, everything from the line

Code: Select all

void StateMachine::process_command(Position& pos, std::string token, std::istringstream& is, StateListPtr& states) {


to the end of the xboard.cpp file?

[janggi-korea]

The ponder stopped again during the game. You need to check the debug file. I used "edit game" to recreate the game, but it marked illegal moves.

process_command ???

What do you mean? Please explain in detail exactly what I need to post.

[H.G.Muller]

I am understanding less and less of what goes on here. In the latest debug log you sent me, the GUI at some points sends an 'accepted setboard', which seems to come out of nowhere. (There was no immediately preceding "feature setboard=1" to which this this should be the reply.) The arrival of this command while SF already started thinking triggers it to send a move that should never have been sent.

The only think I can think of is that the previous debug output line "# command: 'setboard'" somehow triggers this behavior. I was assuming that lines starting with # should always be completely ignored by WinBoard. But this guarantee only exists if the engine sends feature debug=1 at startup. And I now see that SF does not do that. So it could be that WinBoard considers this non-compliant input, and gets upset by it.

So please replace the line

Code: Select all

                << "highlight=1 name=0 sigint=0 ping=1 myname=\""


by

Code: Select all

                << "highlight=1 name=0 sigint=0 ping=1 debug=1 myname=\""


to make sure that WinBoard will ignore the engine messages we added for debugging.

And don't forget to post the source code I asked for here!

[H.G.Muller]

Well, same behavior. It prints a move directly after receiving the '?' command, without waiting for the "rejected GOTMOVE".

Wait! I have an idea! The search doesn't stop because of the processing of the '?' command at all. There is also code in the process_command routine to stop the search just before a move is printed, executed for any command (except ptell) that comes in while the engine is thinking. That would already handle the '?' command. So we should not have put in our own code to do that.

For now, you can try to prevent that duplicate execution of '?' by changing the line

Code: Select all

  if (moveAfterSearch && token != "ptell")

to

Code: Select all

  if (moveAfterSearch && token != "ptell" && token != "?")

This does not solve the problem for other commands that would arrive while the engine is thinking, though. I will devise a more fundamental solution tomorrow (as this will be complex).

[H.G.Muller]

OK, I cooked up something. Try to replace the initial part of the routine process_command upto and including the line with "protover" in xboard.cpp by this:

Code: Select all

void StateMachine::process_command(Position& pos, std::string token, std::istringstream& is, StateListPtr& states) {
  if(token == "rejected")
  {
      is >> token;
      if(token != GOTMOVE) return; // [HGM] all other feature rejections are ignored
  }
  if (token == GOTMOVE && ponderMove == "") // [HGM] a search for thinking announces its termination
  {
      // abort search in bughouse when receiving "holding" command
      bool doMove = token != "holding" || Threads.abort.exchange(true);
//      Threads.stop = true;
//      Threads.main()->wait_for_search_finished();
      if (doMove)
      {
          Move m = Threads.main()->bestThread->rootMoves[0].pv[0];
          if(m != MOVE_NONE)
          {
              sync_cout << "move " << UCI::move(pos, m) << sync_endl; // print move
              do_move(pos, moveList, states, m);                     // and do it ourselves
              moveAfterSearch = false;
              if(Options["Ponder"] &&
                 (Threads.main()->bestThread->rootMoves[0].pv.size() > 1 ||
                  Threads.main()->bestThread->rootMoves[0].extract_ponder_from_tt(pos)))
              {
                  m = Threads.main()->bestThread->rootMoves[0].pv[1]; // ponder move
                  ponderMove = UCI::move(pos, m);                     // remember it (indicates we are pondering)
                  sync_cout << "Hint: " << ponderMove << sync_endl;   // print it
                  do_move(pos, moveList, states, m);                  // perform it
                  limits.startTime = now(); // As early as possible!
                  Threads.start_thinking(pos, states, limits, true);  // and start pondering
              }
          }
      }
  }
  else if(token == GOTMOVE)
      ponderMove = "";
  else if (token == "protover")


This has done away completely with the 'moveAfterSearch' signalling that SF originally used; the decision for whether a move will be output by the engine will be purely taken on the basis of whether there is a ponderMove specified (which would indicate we are pondering on it), and only happen at the moment the engine receives (through the GUI) a confirmation that a search ended (through "rejected GOTMOVE=1"). So that a move is indeed available, and no spurious moves can be sent. The ponder search (which starts after outputting the move) will thus also only be started after all commands associated with terminating the previous search have been received, so that no 'surprise command' will be able to disturb it.

A ponder search can only be terminated by a usermove (as a hit or a miss), or a "force" command; the code for handling these commands was already such that it takes care of initiating the search abort and retracting the ponder move when necessary. This leaves ponderMove non-empty, though, so that the GOTMOVE generated by terminating the ponder search will know that it was a ponder search, and reset ponderMove without emitting a move and starting a new ponder search.
