Winboard janggi "OpeningBook" compatibility development

Postby janggi-korea » 31 Oct 2020, 14:23

I uploaded the engine file and source code to Google Drive for openingbook development.
The engine developer solved the "Ponder" problem, and uploaded the solved engine(1031.exe) and the we developed engine(1030.exe) together.
This is because the current GitHub source has broken compatibility with the source we developed.
So I recommend using the engine and source code of engine developer.

1. Ponder solved-GitHub compilation engine and source: 1031-Fairy-Stockfish-master.zip / 1031.exe

2. Currently we are working on-engine and source : 1030-Fairy-Stockfish-master.zip / 1030.exe

note. Breaking compatibility means that merging is difficult(GitHub Update). I tried merging several times, but it failed thread file and the position file.
Both engines work fine on winboard.

When starting with "just view or edit game files" on the recently updated winboard, I found an error that could not read the PGN game files I saved.
PGN can be read normally after engine load, but cannot be read without engine load. Could you please check this first?

Re: Winboard janggi "OpeningBook" compatibility development

WinBoard doesn't like that the name specified in the Variant tag of the PGN is "janggimodern". It doesn't recognize that as the name of any standard variant; it needs an engine to tell it that it should treat this as if it is janggi. Because it doesn't recognize the variant name, it assumes that it is normal Chess, and then it doesn't recognize the piece IDs anymore. It is a bit inconvenient that this does not work without an engine.

If the Varaint tag would have said 'janggi', WinBoard would have no trouble reading the game. So perhaps it should write the name of the parent variant in the tag, when it saves the game of an engine-defined variant. But then the information on what sub-variant it was would be completely absent.

So I suppose we need to specify two variants with a PGN: the engine-defined name (janggicasual) and the parent variant.

Oh sorry, I asked the same question. I forgot this.

I think, the important point in writing the "openingbook" is the win or loss of the game. And Winboard seems to automatically save the game for which the win or loss is determined. So, first of all, I want to make a suggestion.
In the Action menu, Resign (F9) works.
But Adjudicate to white/black/draw doesn't work.
Can you activate this? Perhaps this feature will be available in online games. However, janggi currently does not have a server that connects online games to Winboard.
So, I want to use it as a win/loss decision in saving pgn. Or is there a way to re-judgment on Winboard for already saved pgn?(Win/L/D)
Or is there another way? My meaning is about manual judgment.

PS.janggi PGN does not work with Load Game-"Find Position".

The adjudicate W/L/D was intended for engine-engine games; when playing yourself (against engine or on-line) the rules of chess do not allow a player to one-sidedly decide he has won, or even in most psituations that it should be a draw. You can only declare your own loss.

But you are right: in Edit Game mode it would make sense to allow setting of an arbitrary result too. I guess no one has ever requested that before, because you can simply wait for the player you want to lose to get on move, and then resign. But I will check if this menu item can be easily made to work in Edit Game mode too.

[Edit] OK, I see what the problem is. When running without engine the entire Action menu is disabled, so that you cannot get to the adjudication menu items (which would never be disabled individually). And you can also not get to 'resign'. So it is not so much dependent on the Mode, but on whether there is an engine available. This is a bit hard to change, as it would require complete reorganization of the menus. But you can easily work around it by starting WinBoard with an engine.

[Edit2] There seem to be several things broke in the current WinBoard version, some of which I thought were working before. The 'find position' indeed doesn't work for me either. It could be that it doesn't take account of the FEN tag in the PGN, when it is playing through the games to see if the sought position occurs in them. I will check it out.

I think Winboard's Monte-Carlo algorithm book generator is a very innovative method. (but need to long time) :D
Korea's janggi program hasn't even tried it.
The Korean janggi program simply used the move of the number of times they game most as a book. (Probability of moving)
The weight of win/loss/draw is a very advantage in book writing.
So I want to use "Adjudicate to white/black/draw" not only in game editing mode, also want when the engine is loaded. And it would be nice if I could change the win or lose or add to correct the error.
For example, cute-janggi can also be used in engine vs. human games.

The "Find Position" It was also not available in previous versions too. So I added the code to the [VariantMen "N:nN;R:RB;A:WF;B:mafsmafW;P:fsWfF;C:pRpB;K:WF"] in pgn file so that the location can be recognized.
But I didn't find all the locations. I only found some locations.
Maybe I couldn't find the mirroring location.

The VariantMen tag does more harm than good, now that WinBoard knows the exact Janggi rules. (The same was true for the engine's 'piece' commands.) The move notation that can be given there is not precise enough to define the exact Janggi rules, so the moves are only approximate, and (for example) make the Rook move diagonal everywhere on the board. Some of the games in the TOTAL.pgn refused to load with legality testing on, because the VariantMen tag made WinBoard think the King was left in check by a Cannon, while in fact the check was blocked, because Cannons cannot jump other Cannons.

The Janggi rules are so special, that currently the only way to let WinBoard use them is to make it use parent variant 'janggi'. So I think we should have a ParentVariant tag in the PGN. (Or perhaps call it 'VariantFamily'.)

I solved the find position problem.
It seemed there was a problem with "Total.pgn" I gave you. This is because it was not a PGN format that was fully compatible with Winboard.
So I changed it to Winboard PGN format.
The method was saved again using "Save Selected Games".
And I was able to find the position using "Match if Position is subset" and "Also match reversed colors" and "Also match left-right mirror image".
"match exact position" doesn't work. and the newly created PGN only displays the results of the game "stalemate" and "checkmate".

The important point is that if I played the game with another janggi variant and saved it, I have to text edit the janggi variant with the default janggi to find the position of the saved file.(need to edit with janggi variant/ janggimordern->janggi) . Book making too
And even if I loaded another janggi variant of the engine, I could also find the position too.

Anyway I found a temporary workaround.

After all, this is a compatibility issue with janggi variants as you said.

I have uploaded a new WinBoard-AA package, which should include a [VariantFamily "janggi"] tag in any PGN it saves in one of the other 3 Janggi flavors. PGN games that contain this tag after the normal Variant tag (which specifies the engine-defined name, like 'janggicasual') can now be loaded when running without an engine.

Thank you very much. New ver. Works fine.

[about book]
If there is a tool that can convert PGN files into mirrored coordinates, this seems to be a very easy problem.
If i combine the PGN file with changed coordinates and the default PGN file and use it as a book, all problems will be solved.
This is because if you use the "-symBook" option now, an error occurs due to duplicate coordinates, and the movement counter of the already created book information is not updated.
In principle, the final movement counter is the sum of base + mirroring.
But when editing a book, i also need to edit the mirror coordinates. I do not know the correct answer. Let me think of an idea.

[about rule]
Request to modify Winboard janggi rules.
When playing Ai vs Human with the Auto flag unchecked, the game is a draw if use turn PASS when the human has used up all of his time.
"Message: {Both players ran out of time} 1/2-1/2"

janggi : When the Auto flag unchecked, the human player has no time limit, and PASS can also be used.
Perhaps the rules of chess still exist. Request for modification according to Janggi rules.

The behavior that you describe was unintended in the first place. In Chess turn passing was only allowed as an analysis tool, to recognize threats, and there is no flagging in anlyze mode. So when playing, clicking the clock can only mean an attempt to claim the opponent's time forfeit. When playing Janggi there are both time forfeits and turn passing, so the issue arises to determine what a clock click means. If the players are not out of time, then it should obviously mean a turn pass. But is a player is out of time, there has to be a rule for resolving the ambiguity. Clicking the clock that is already running is not a turn pass, and can thus always remain claiming of a time loss. Clicking of the non-running clock should mean a turn pass in games where a turn pass is legal. If that player is also out of time, you can always claim it after you have transferred the turn to him. But there would be no alternative to entering a turn pass.

This whole business of claiming a time forfeit seems silly to me in the first place. (But it has always been part of WinBoard.) If you wanted to stricly enforce the time limits, you should switch autoFlag on. What would be the point of switching it off, and then claiming it by hand? What is the point of the human claiming a time forfeit in a human-engine game anyway? For one, engines are not supposed to ever overrun their time: they should be able to move in milliseconds, if needed. Engine forfeits usually only occur when the engine crashes without terminating. And even when they would forfeit, they are not sentient beings, (especially after they crashed...), and will not be able to realize whether they have lost or won, while the human would already know he had won before he attempted to claim it through a clock click.

Okay. understand. If you fix this, I'm afraid run into problems with the rules of chess too.
So, when the time runs out, I will "pass" by using "type in move" menu.

I guess that in the Palace Pawn moves can need more disambiguation in their notation than elsewhere, because of the extra diagonal moves. For now (in the newly uploaded WinBoard-AA.zip) I solved it by always writing a fully disambiguated move (i.e. mentioning both file and rank of the square of origin) when the move starts in the Palace and ends on the last two ranks. This creates longer notation than necessary most of the time, but it should never leave any ambiguity.

Re: Winboard janggi "OpeningBook" compatibility development

Postby janggi-korea » 05 Nov 2020, 07:57

Thanks. :D All movement rules for janggi pieces are now fully compatible on Winboard.

Now I am talking about the janggi win-loss rule.
I converted my "Total.pgn" file into a pgn file for Winboard. Some confirmations are required here.

1. Win/loss processing problem: When converting to Winboard's pgn, only chekmate and Stalemate win/loss are judged and saved in Winboard.

So I used a filter and saved only the 1-0 result pgn file separately. And the game result was modified by text editing. [Result "1-0"]
The problem arises here.
Some janggi games are judged by the winboard {stalemate} 1/2-1/2.
This is a problem with the janggi win-loss rule. Winboard is judged as a draw when "{stalemate} 1/2-1/2" cannot move.
Perhaps it is the rule of chess.
However, in the janggi, the turn pass is possible, so it is not a draw. I show 2 sample FEN.

3k5/6R2/2c6/9/4H4/4C4/7P1/4K4/9/9 b 2
9/3k5/5R3/9/9/9/9/9/4K4/5C3 b 0

If the movement proceeds from the FEN position, WHITE will surely win.
However, because Winboard automatically judges it as {stalemate} 1/2-1/2, Janggi win-loss rules and problems arise.
In the end, if cannot move, must Resign or Pass.
So.. for janggi I ask to delete the {stalemate} 1/2-1/2 automatic judged.

======================================================================================================

Correct understanding and problems of -sym command in janggi.
1. janggi has 16 starting positions. And it is divided into 10 groups.
What the group means is the horizontal mirroring reverse position.
To make it easier for you to understand, I will explain "Flip View" as an example.
"Flip View" first changes up and down. And the left and right change.
The group simply means the FEN value with the left and right reversed.
Group with only one FEN value has the same FEN value as the left and right inversion.

reha1aher/4k4/1c5c1/p1p1p1p1p/9/9/P1P1P1P1P/1C5C1/4K4/REHA1AHER w 0 1


So then I tested the -sym command.
[ Group 7 ] : Winboard default starting position

[Event "?"]
[Site "?"]
[Date "?"]
[Round "-"]
[White "?"]
[Black "?"]
[Result "*"]

There are 6 movements. And exactly as shown below, the six movements of symmetry are displayed in the book and need to be moved.

[Site "?"]
[Date "?"]
[Round "-"]
[White "?"]

However, the movement of the book is as follows. And the book is disconnected.
99.9% 1 ih6

In addition, a movement record is created that ignores the FEN value of each group.


Now, I will explain [Group 2] again, where the inversion position is not the same.

Only the moving coordinates of the pieces moving up and down from the center will be the same.

=============================================================================================

I need one last check.

1. When you first start Winboard, it starts from the following position.
[Group 7]: Winboard default starting position
rhea1aehr/4k4/1c5c1/p1p1p1p1p/9/9/P1P1P1P1P/1C5C1/4K4/RHEA1AEHR w 0 1

I made a book, and it doesn't show up in the default start position when starting Winboard (it doesn't work).
So I have to read the FEN file again.(FEN file with default starting position saved)
And I could use the book again.
This means that Winboard has a problem in recognizing the starting position and the default position of the newly created book differently.
In other words, it is the same FEN, but it means that the display of the book at the default start and when book read through the file is displayed differently.

If you have any questions, please explain to me.


PS. Piece "Menu instead of Sweep Select" disappeared from general options after Ver.2020.409. Since... janggi has a lot of pieces, this was a very useful feature. Can you add it again?

Re: Winboard janggi "OpeningBook" compatibility development

I had not gotten back to looking at the book problems yet, but I think I am ready to do that now. Before there were still too many problems with the engine overruling the symbol assignment (affecting the book encoding), and games refusing to load due to move notation problems.

Last time I tried creating a Janggi book I noticed the same problem as you: I tried to convert TOTAL.pgn to a book, and I got a book file. But no moves for the default initial position were shown. When I was investigating that I noticed that many of the games in TOTAL.pgn did not specify a result, and the results are used when creating a book from PGN. But when I then just copied the first few games of TOTAL.pgn to another file, added a result, and tried to convert that to a book, I get a completely empty book file! (Length 0 bytes.) I have not been able to figure out why this happens; adding some print statements in WinBoard for debugging showed that the the moves of the games are added to the memory buffer that contains the book, so apparently things go awry when that memory buffer is written to file. But that was as far as I got.

It is also still a mystery why 'Find Position' does not work for individual positions.

I have not tested yet if this also happens in other chess variants, or that this is unique to Janggi. It really should not make any difference what variant it is used for.

I will keep working on both problems, but I don't have very much time today to do that.

summary of the contents you need to check when you have the time.

1. The book is created normally, and it works fine.
It can only work after FEN (Starting Position) file loading it.
I uploaded a book file and a pgn file for Winboard and the latest version of the engine to Google Drive for your testing. I specified all the games results in the pgn file.
However, I think,, not all positions. Only some positions were made into books. Because compared to the number of games, the number of positions created is insufficient. I don't know exactly this.
[Position FEN file.zip / new book.bin / new total.pgn / 1104.exe]

2.Thresholds-Match if position is subest
Check: Also match left-right mirror image
Using the above option works fine. (Find position)

3. Please delete the "{stalemate} 1/2-1/2" automatic judged function.

4. Start of book compatibility development (Mirroring position)

5. "Menu instead of Sweep Select" => Menu restoration request

I merged your code with the latest commit.
Can you confirm this?
I used game editing, but ponder didn't stop.
And on Winboard, the order of playing the engine output window changed from black to white. I have a problem with something.
Perhaps this could solve the reason why the engine keeps pondering in the middle of the game.
I uploaded the source to Google Drive.(Fairy-Stockfish-master muller.zip)

From what I see it seems the engine ignores the 'force' command while thinking. (It was not pondering here.)

I thought we had this working before? Or was that just for a 'force' during pondering? I completely lost track of what source code we are using now. Can you post xboard.cpp here?
