实验的特定输入 return 解析器错误

Specific inputs of experiment return parser error

#!/bin/bash

                    let "m=m+1"
                    echo "m=$m"
                done

                ratio=$(echo "scale=10; ($ratio) + ($step)" | bc) #float points arithmetics are different

我基本上只是 运行ning 一个实验,我 运行 一个包含不同输入的文件。该代码适用于某些值,而对于某些值,它只给了我:

(standard_in) 1: parse error

在我的结果文件中,这是我的输出:

50 0 1 0
21.82
50 0 1 .2
27.08
50 0 1 .4
40.89
50 0 1 .6

我正在进行的实验 运行ning 总是在相同的输入值(输出文件中打印的最后一个)停止,然后从那里开始都是 解析器错误 !为什么要这样做?我该如何解决?我在这里尝试了针对类似问题(与 bc 相关)找到的多种解决方案,但 none 有效。

我怀疑它与以下行有关:


executiontime=$(timeout 500 gtime -f "%U" /Users/ouafaelachhab/Desktop/SemanticLocality/optimathsat-1.6.2-macos-64-bit/bin/optimathsat &1 >/dev/null)

我将其作为输出(注意 I S S U E 是如何逐行打印的)
