num_lineups is the total number of lineups
num_lineups = 3;

num_overlap is the maximum overlap of players between the lineups
num_overlap = 6

#number of hitters in the stack (number of consecutive hitters in the hitting order)
stack_size = 5;

#FORMULATION: formulation is the type of formulation that you would like to use.

results

Answer 1

这个答案的两个部分：

关于眼前的问题：tic 和 toc removed in Julia 0.7 支持 @time 宏。所以不要写

tic()
my_function_call(arg1, arg2, ...)
toc()

你现在写

@time my_function_call(arg1, arg2, ...)

一般来说，当从旧的 Julia 版本更新代码时，建议首先验证它确实可以使用开发它的版本工作，然后再继续 version-by-version。这样，当您的代码中的某些内容在未来版本中不起作用时，您将收到弃用警告。要查看此示例，这里是 Julia 0.6.4：

julia> tic()
0x00043e524144a02b
julia> toc()
elapsed time: 2.043187801 seconds
2.043187801

这是 Julia 0.7：

julia> tic()
┌ Warning: `tic()` is deprecated, use `@time`, `@elapsed`, or calls to `time_ns()` instead.
│   caller = top-level scope at none:0
└ @ Core none:0
0x00043e951b0f07c4

julia> toc()
┌ Warning: `toc()` is deprecated, use `@time`, `@elapsed`, or calls to `time_ns()` instead.
│   caller = top-level scope at none:0
└ @ Core none:0
elapsed time: 1.73983 seconds
1.73983

现在你可能会想“哦，哇，这很烦人，因为我想更新到 1.8 版”，但好消息是 Julia 遵循 SemVer，1.0 之后的所有内容都是次要版本更新（相当比一个主要的），根据 SemVer “以向后兼容的方式添加 [s] 功能”。

0.7 是一个过渡版本，它基本上为用户准备了突破性的 1.0 版本——您可以将其视为“带有弃用警告的 1.0”。因此，让您的代码进入 post-1.0 Julia 版本的可用状态非常有帮助。

当然，这并不是说如果您打算继续使用您的代码就必须就此打住。 Julia 正在快速发展并在 1.0 和 1.8 之间取得了巨大进步，在某些情况下，您会希望更改代码以利用新功能 - 但从工作基础上做到这一点要容易得多，因此修复弃用警告在旧版本上查看是第一步。
