国际象棋引擎选项配置

Question

我修改了 Goratschin Chess 代码，使其可以同时运行 8 个国际象棋引擎，并且可以运行；

但是在代码中缺少了每个单独的国际象棋引擎的选项管理，因此系统读取每个与国际象棋引擎相关的exe文件的默认参数（hash，thread，syzygyPath，evalfile nnue）

要求 ：

1. 有谁知道如何将自定义参数（哈希、线程、syzygyPath、evalfile nnue）插入以下 Python 代码？ 包含路径和国际象棋引擎名称的起始文件是 goratschinLauncher.py ：

#!/usr/bin/env python3

# to create an EXE from this file, do:
# pip install pyinstaller
# pyinstaller -wF goratschinLauncher.py
# copy .exe from 'dist' directory in root directory

import argparse
import logging
import sys
import datetime

from goratschinChess import GoratschinChess


# folder and file names for the engines.
engineFolderDefault = "C:/Temp05/ChessCombi2/engines/"
engineFileNames = ["Combi01", "Combi02", "Combi03", "Combi04", "Combi05", "Combi06", "Combi07", "Combi08"]


if __name__ == "__main__":
    parser = argparse.ArgumentParser(description='UCI ches engine.')
    parser.add_argument('-log', help='Name of log file.')
    parser.add_argument('-v', '--verbose', action='store_true', help='Verbose output. Changes log level from INFO to DEBUG.')
    parser.add_argument('-e', '--engineFolder', help='Engine folder.')
    parser.add_argument('-m', '--margin', type=int, default=50, help="Margin in centipawns of which the counselor's eval must be better than the boss.")
    args = parser.parse_args()

    print('args :'  + str(args), flush=True)

    # configure logging

    logger = logging.getLogger("goratschinChess")   
    logger.setLevel(logging.DEBUG if args.verbose else logging.INFO) 
    if args.log:
        now = datetime.datetime.now()
        f_handler = logging.FileHandler(args.log + '-' + str(now)[:10] + ".log")
        f_format = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
        f_handler.setFormatter(f_format)
        logger.addHandler(f_handler)
    
    enginesDir = args.engineFolder if args.engineFolder else engineFolderDefault
    
    print('engine folder specified: ' + str(enginesDir), flush=True)

    # start the goratschinChess engine
    GoratschinChess(enginesDir, engineFileNames, args.margin).start()

第二个文件的名称是 goratschinChess.py 但由于它太长，我标记了可以查看它的链接以及第一个文件： https ://github.com/scacchig/Synergy-Chess

启动每个引擎并根据给定的选项为其设置选项。

goratschinChess.py修订

添加选项参数。

def __init__(self, engineLocation, engineNames, margin, options):
    self.engineFolder = engineLocation
    self.engineFileNames = engineNames
    self.score_margin = margin / 100 # given in centipawns, default: 50
    self.options = options

使用用户选项初始化引擎。 当我们收到 isready 命令时，我们将设置选项。

def _mainloop():
    ...
    elif userCommand == "isready":
        # Set user options to engines.
        for i, engine in enumerate(self._engines):
            if i >= len(self.options):
                break
            optkeys = list(self.options[i].keys())
            for optname in optkeys:
                engine.stdin.write(f"setoption name {optname} value {self.options[i][optname]}\n")
                engine.stdin.flush()
                print(f"info string {self.engineFileNames[i]}: setoption name {optname} value {self.options[i][optname]}", flush=True)
        self.send_command_to_engines(userCommand)
        emit_and_log("readyok")

从引擎记录 NNUE 信息。

def _check_result():
    ...
    elif info.startswith("info string NNUE evaluation "):
        emit(info)

在启动器中定义选项。

goratschinLauncher.py修订版

    options = {
        0: {"Hash":128, "EvalFile": "nn-6877cd24400e.nnue"},
        1: {"Hash":128, "EvalFile": "nn-d0b74ce1e5eb.nnue"}
    }

    # start the goratschinChess engine
    GoratschinChess(enginesDir, engineFileNames, args.margin, options).start()

Arena 日志，在收到 isready 命令后，我们设置我们的选项。

2022-05-30 19:43:38.593-->1:isready
2022-05-30 19:43:38.909<--1:info string SF_0: setoption name Hash value 128
2022-05-30 19:43:38.912<--1:info string SF_0: setoption name EvalFile value nn-6877cd24400e.nnue
2022-05-30 19:43:38.915<--1:info string SF_1: setoption name Hash value 128
2022-05-30 19:43:38.919<--1:info string SF_1: setoption name EvalFile value nn-d0b74ce1e5eb.nnue
2022-05-30 19:43:38.922<--1:readyok

引擎现在使用指定的 nnue。

2022-05-30 19:44:03.075<--1:info string NNUE evaluation using nn-6877cd24400e.nnue enabled
2022-05-30 19:44:03.077<--1:info string NNUE evaluation using nn-d0b74ce1e5eb.nnue enabled

测试结果

GoratschinLauncher 播放器使用 2 个引擎。
