Dafny验证程序：VSCode与命令行输出

Question

我正在Windows 10的Visual Studio Code 1.43.2中使用Dafny。

我的算法已通过约150个证明义务的验证。然后，我添加了一个ghost变量和更多的引理，但没有更改算法。我现在在一个不变式和循环的reduces子句（这些是以前证明的）上遇到超时错误，如下所示。

添加其他assert甚至assume语句只会导致更多的不变式超时。因此，我尝试使用/compile:0（因为我有两个无主体方法）和/tracePOs选项从命令行运行Dafny。我得到以下输出：

Dafny program verifier finished with 17 verified, 0 errors

这是否意味着算法是正确的，但是证明义务的数量对于VSCode来说太多了？有没有什么办法解决这一问题？我尝试修改settings.json文件以增加时间限制，但是我不确定默认值是什么，以及这样做是否正确：

{
    "dafny.basePath": "c:\\Users\\zaina\\.vscode\\extensions\\correctnesslab.dafny-vscode-0.17.1\\dafny\\dafny",
    "[dafny]": {},
    "dafny.serverVerifyArguments" : ["/timeLimit:110"]
}
