Hi Ed
That's not the case. My source book is called white_3.bin
If I choose the option 'B' to calculate new weights everything works fine. And the moves are correctly displayed in SCID. It's only when I use the option 'V' that I got these strange characters. I will send you the bin books to your gmail adress so you can check for yourself.
Also a description of how I made them.

Thank you for this great tool :)
I'd like to have an option to set the Syzygy path and contempt in the Poly gui - it would make it more convenient in my opinion (though only useful for very deep analysis).
I plan on doing a "Contempt book" with C=40 for very aggressive play :twisted:

Downloaded poly 1.2 today. Tried its feature to add score to polyglot book using poly.

1. I have polyglot book called d.bin
2. Use poly to generate epd file using 10.epd
3. The generated epd file is d.epd
4. Use poly to analyze d.epd at 2s/position
5. The epd with analysis is called new.epd
6. Use poly to import the analysis in new.epd to d.bin

I tried the book in Deuterium using BestScore move selection option and this is its log.

Code: Select all

>> position startpos
string received: go wtime 300000 btime 300000 winc 100 binc 100

move g2g4 is selected having the best score!!
<< bestmove g2g4
The move g2g4 was selected because this move has the best score.

When I checked the new.epd, this is the file that was imported to d.bin, I cannot find a startpos epd with move g2g4. But I can find 2 epd from startpos.
Here are the 2 analyzed epd from new.epd

Code: Select all

rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - po 5662400; id sf10x.exe; bm d2d4; ce 39; acd 19; c1 Threads 1, Hash 256, Time 2000ms;

Its only d2d4 and e2e4. There is no g2g4. Could this be a bug in poly?

If I try ProDeo.bin I get this.

Code: Select all

<< bestmove e2e4
Looks normal.

Notes:
1. The d.epd generated by poly with the help of 10.epd generated duplicates. Duplicates should be removed before analyzing it. In my case I did not delete it, since I assume that poly will remove the duplicates in the generated epd file.
2. But there is a menu in poly that seemed to remove the duplicates, it is called Remove doubles.

Opening book: prodeo.bin with my engine.

# key: 463b96181691fc9c

# move=d2d4 weight=51.60% score= 4096 depth=20 learn=0

# move=g1f3 weight= 2.31% score=64767 depth=20 learn=0
0 0 0 0 (Book move)
Computer's move: d2d4

How do I pass the score to centipawns?
Where do I find prodeo.bin with numbers in learning?

Thank you.

Score in pawn unit.

double score = entries[i].score >= 32768 ? (double)entries[i].score / 65536 - 1.0 : (double)entries[i].score / 65536;

The move g2g4 was selected because this move has the best score.
That's odd indeed.

A possible explanation can be that you haven't cleared the scores (the "Clear Analysis" function) and the "g2-g4" comes from a previous session, although I must say that a score of 0.31 remains suspect.

Maybe you can run it again with "Clear Analysis"?
Could this be a bug in poly?
If the above doesn't work mail me so I can reproduce it.

I always run "Remove doubles", can save much analysis time.

Tried but still same result, I sent a PM with d.bin and new.epd download link.

BTW I tried to import a single epd to d.bin by Import Analysis.
rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - bm e2e4; ce 20; acd 22;
But after checking with Poly statistics, Analyzed Positions is 0. So this was not imported. So what is the requirement of the epd format that can be imported?
