SCIP在自动化测试中编写最佳可行解决方案 [英] SCIP write best feasible solution in automated test

问题描述

基于 http://scip.zib.de/doc/html/中的步骤TEST.php ，我设法使用SCIP设置了自动化测试.但是，我想将解决方案(最可行的解决方案)写到文件中，而不是仅仅获得目标值.无论如何，在自动化测试中有做吗?

Based on steps in http://scip.zib.de/doc/html/TEST.php, I have managed to set up an automated test using SCIP. However, I'd like to write the solution (best feasible solution) to a file, instead of just getting the objective value. Is there anyway to do it in the automated test?

我通过替换

OPTCOMMAND=optimize; write solution myfilename.sol;

但是很糟糕，它似乎不起作用，当我尝试进行TEST = mytest测试时，从输出中看到了这一行

But too bad, it doesn't seem to work, when I tried to make TEST=mytest test, this line is observed from the output

 bash ./check.sh mytest bin/scip-3.1.0.linux.x86_64.gnu.opt.spx default scip-3.1.0.linux.x86_64.gnu.opt.spx 3600 2100000000 6144 1 default 10000 false false 3.1.0 spx false /tmp optimize;
 write: solution is not logged in on myfilename.sol

我知道可以通过交互式shell编写解决方案，但是我正在尝试使测试自动化以检索解决方案和obj值.任何帮助或澄清将不胜感激！

I know it is possible to write the solution via interactive shell, but I am trying to automate the test in order to retrieve both solution and obj value. Any help or clarification will be much appreciated!

推荐答案

由于使用的语法，由于分号，您试图调用一个名为"write"的bash命令，因此出现错误:

You are getting an error because with the syntax you are using, you try to invoke a bash command called "write" because of the semicolon:

write实用程序允许您通过以下方式与其他用户进行通信 将线路从终端复制到终端.

The write utility allows you to communicate with other users, by copying lines from your terminal to theirs.

只需尝试不使用分号;)

Just try without semicolon ;)

更清洁的解决方案是修改文件"check/configuration_tmpfile_setup_scip.sh" 并添加行

The cleaner solution would be to modify the file "check/configuration_tmpfile_setup_scip.sh" and add the line

echo write solution /absolute/path/to/solutions/${INSTANCE}.sol >> $TMPFILE

在退出命令之前.此配置文件设置了一个批处理文件，以向SCIP提供交互式外壳程序应执行的所有命令，并且您可以对任意用户的行为进行建模.

before the quit command. This configuration file sets up a batch file to feed SCIP with all commands that the interactive shell should execute, and you can model arbitrary user behavior.
