将清单中的 Julia 代码转换为伪代码

Question

我正在尝试自动导入用 Julia 编写的代码并将其转换为半伪代码。作为一个最小示例，我尝试复制以下伪代码样式：

我猜这是用这个algorithmx包做的。下图是我尽力复制的这种风格

但是我的代码存在一些小/主要缺陷：

• 我怎样才能将所有非关键字或非函数名称的内容转化为数学？它看起来比字体好多了ttfamily。

• 我在 lset 中定义的顶线没有示例中的那么粗。我知道它在哪里定义，但不知道如何更改它的宽度。

• 没有必要复制AlgorithmX示例中的注释风格。

CountRoutes2.jl

请注意，为了将伪代码转换为可运行的 Julia 代码，必须进行一些细微的更改。

cache = Dict()

function countRoutes(m,n)
    if n == 0 || m == 0
        return 1
    end

    try
        return cache[(m, n)]
    end

    cache[(m, n)] = countRoutes(m, n - 1) + countRoutes(m - 1, n)
    return cache[(m, n)]
end
