Banksia - Yet another Chess Tournament Manager

phhnguyen · Post by **phhnguyen** » Wed Jul 10, 2019 3:33 am

I have just released version 1.5 to support WinBoard protocol and Polyglot opening books. So far all main/big chess functions are completed.

For coming versions I have been working on a special function to auto generate Json files which are mainly used to configure engines and control tournaments.

Hope to get some feedbacks / bug reports from you soon

Hi,

Interesting project.

I tested it in Linux and it worked fine except for one compile problem. I also added CMake build files to make compilation in Linux easier. I have created a pull request that you may want to review.

Wow, thank you. I have never written a makefile myself before

I have just released version 2.0. The new feature is to auto-generate JSON files which are used to play tournaments. Instead of spending hours or even days to create manually parameters for command line and/or JSON files, now all are auto-generated in few minutes.

Bellow is the introduction from the Readme:

Auto generate JSON files
------------------------------
A chess tournament may have tens or even hundreds of chess engines. Each engine has name, command line, working folder and may have tens parameters. Any wrong in data may cause engines to refuse to run, crash or run with wrong performances. However, writing down manually all information into a command line and/or some JSON files is so boring, hard job and easy to make mistake (from my experience, it is not easy to find and fix those mistakes). Defend on experience, it may take from hours to days to create a runnable configuration for a new tournament. Furthermore, new engines may frequently add or change parameters without notice to users.

Banksia can help to solve the above problems by generating/updating automatically all data needed for a tournament. If the old data exists, Banksia can update it without erasing nor modifying non-involving information. Thus users can update frequently their data.

What a user should do to generate or update JSON files:
- copy all engines into a folder (including their belonging files as well as all subfolders)
- run Banksia with that folder as a parameter and wait for few minutes. That all!

For example:

Code: Select all

banksia -u -c 4 -d c:\allenginefolder

Bankisa scans that given folder, including all subfolder for all executable files, then runs those files to detect if they are chess engines, what their chess protocols and options are. Bankisa can run and test concurrently those files (the parameter -c 4 means that is a concurrency of 4) to speed up the process (for a tournament within 20 engines, 4 concurrencies all may take about 1 - 5 minutes). All information is saved or updated into two key JSON files (if their paths are not specified, they will be created in the current working folder).

If users don't want Banksia to scan (or engines are not scannable, or located in different folders/drivers) or run not-involving executable files, they can create a simple and short JSON file (file engines.json) contains only commands of engines they need. Banksia will verify and fill all other information.

Code: Select all

[
    { "command" : "d:/stockfish/stockfish.exe" },
    { "command" : "c:/match/crafty25.3" }
]

Right after generating JSON files, users can start their tournaments:

Code: Select all

banksia -jsonpath c:\tour.json

Of course, users can edit those JSON files such as removing redundant, unused fields, re-order them to be easier to read! Some data fields are written down in empty forms (e.g. opening book folders) and need to fill in.

Version 2.2! It supposes knockout (elimination) type and resumption last incomplete tournaments. There are also compiled binaries for Mac OS and Windows 64 bits you can quickly try.

Now Bansia has almost all features/functions I have dreamed for: small, fast, portable, easy to use, easy to integrate to other systems, resumable, able to automatically generate all configurations, files which are needed for tournaments.

Hope it could help users to create chess tournaments with much more ease and fun!

I will slowdown its development a bit, focusing on fixing bugs and small improvements.

All bug reports, suggestions, contributions are more than welcome!

Banksia 3.0 is released!

New main features:

Swiss tournament

detect opening names, variants, ECOs (save to PGN files)

profile (for Windows only): detect the number of threads, memory and CPU usage for engines

adjudication: finish a game if its length exceeds the given limit or the position hits Syzygy tablebase

improve JSON updating: keep almost all user-added information (such as notes/comments)

When working with engines, I am always curious about how they use memory, CPU, how good/effectiveness my engine compares to others, if I do something wrong about their settings for tournaments... The new feature 'profile' can provide some information for those questions. Below is an example (settings of all engines: 1 cores/threads, 64MB memory/hash).

I generated engines json file and there is

Code: Select all

"inclusive players" : 
  {
    "guide" : "matches are counted with players in this list only; side: white, black, any",
    "mode" : false,
    "players" : [],
    "side" : "black"
  },

Could you explain what is this?

I am actually looking for a setting where 2 engines play each other, but sides don't switch. Example first player is engine_white against second player engine_black, They play some games but engine_white will always play as white and engine_black will always play as black. I will run this from a pgn opening suite. Is this possible in Banksia 3.0?

phhnguyen · Post by **phhnguyen** » Tue Jul 30, 2019 3:28 pm

"inclusive players" is used to lock an (or some) engine to matches, including sides. This function can help in your case. To make two engines play again each other which one (engine A) always plays on white side (it is locked to all games and locked to one side), you may edit some fields as below:

Code: Select all

  "base" : 
  {
    "concurrency" : 2,
    "games per pair" : 20,
    "ponder" : false,
    "resumable" : true,
    "type" : "roundrobin"
  },
  
  "inclusive players" : 
  {
    "mode" : true,
    "players" : [ "engine A" ],
    "side" : "white"
  },

  "players" :
  [
      "engine A",
      "engine B"
  ],

For total 20 games ("games per pair") of the round-robin, Banksia will discard 10 games based on the condition in "inclusive players" and play only 10 games. Simply double the number of games you need.

Tip: Sometime I set that number ("games per pair") very large, say 20000 then run it, the tournament may take days to complete. Whenever I want current result, just type from keyboard "status", Banksia will print out that result and I can decide to stop or continue.

To use a PGN opening book:

Code: Select all

      {
        "mode" : true,
        "path" : "your_path_to_pgn_opening",
        "type" : "pgn"
      },

Hope it can help and have fun

My c++ is a bit rusty, but casting them explicitly seems to do the job, but I get more of this error after I fixed them

Thanks for your report. I have fixed some bugs/issues and tested on my Ubuntu 12 using gcc/g++ 6.2.0.

To compile you may use cmake. Another way is to use the script c.sh in the project folder:

Code: Select all

sh c.sh
