关于遗传算法的一个简单图表的帮助

我想要制作下图。

感谢以下评论和一个例子TeXample.net，我编写了以下代码。存在一些问题。我该如何修复它们？

\documentclass{article}
    \usepackage[utf8]{inputenc}
    \usepackage{tikz}
    \usetikzlibrary{shapes,arrows}

    \tikzstyle{frame} = [
        rectangle, draw, 
        text width=2em, text centered,
        minimum height=4em
    ]
    \tikzstyle{line} = [draw, -latex']


\begin{document}

\begin{tikzpicture}[node distance = 3cm]
    \node [frame] (pop) {Population};
    \node [above of=pop, left of=pop] (init) {Initialisation};
    \node [below of=pop, left of=pop] (term) {Termination};
    \node [frame, above of=pop, right of=pop] (parents)  {Parents};
    \node [frame, below of=pop, right of=pop] (off)  {Offspring};

    \path [line] (parents) -- node[right,pos=.4] {Recombination} node[right,pos=.6] {Mutation} (off);
    \path [line] (init) |- (pop);
    \path [line] (pop) -| (term);
    \path [line] (off) -| node[below,pos=.25] {Survivor selection}(pop);
    \path [line] (pop) |- node[above,pos=.75] {Parents selection} (parents);
\end{tikzpicture}

\end{document}

这是我的拥抱输出！

我对您的示例中的文本宽度和节点距离设置做了一些调整，已经达到了几乎相同的效果，但您可能想将箭头放大一点？

我使用以下方式在线更新写LaTeX， 看这里：

附有屏幕截图原始 wL 截图 更新：感谢对 wL 文档进行编辑的人，他们得到了下面显示的更新图像，这非常接近所需的结果更新了 wL 截图

\documentclass[margin=3pt]{standalone}
\usepackage[utf8]{inputenc}
\usepackage{tikz}
\usetikzlibrary{arrows,shadows,positioning}

\tikzset{
  frame/.style={
    rectangle, draw, 
    text width=6em, text centered,
    minimum height=4em,drop shadow,fill=lime!40,
    rounded corners,
  },
  line/.style={
    draw, -latex',rounded corners=3mm,
  }
}

\begin{document}
\begin{tikzpicture}[font=\small\sffamily\bfseries,very thick,node distance = 4cm]
\node [frame] (pop) {Population};
\node [above=2cm, left of=pop] (init) {Initialisation};
\node [below=2cm, left of=pop] (term) {Termination};
\node [frame, above=2cm, right of=pop] (parents)  {Parents};
\node [frame, below=2cm, right of=pop] (off)  {Offspring};

\path [line] (parents)
 -- node[right,align=left,pos=.5] {Recombination\\[3mm]Mutation}
 (off);
\path [line] (init) |- (pop.170);
\path [line] (pop.190) -| (term);
\path [line] (off) -| node[below,pos=.25, align=center] {Survivor\\ selection}(pop);
\path [line] (pop) |- node[above,pos=.75, align=center] {Parents\\ selection}(parents);
\end{tikzpicture}
\end{document}
