用方形连接绘制流程图

Question

我试着在提供的链接上画一个图，从“行为”到流程图开头的菱形决策，但我失败了。我想画一个连接箭头从方块到菱形，而不跨越其他方块。有人能帮我做这件事吗？

如果我理解weel，也许添加一些隐藏节点可能会有一些帮助：

\documentclass{article}
\usepackage[utf8]{inputenc}

\usepackage{tikz}
\usepackage{csquotes}
\usetikzlibrary{shapes,arrows}

\input{config}

\begin{document}
\begin{figure}[!htp]
    \centering
    \begin{tikzpicture}[node distance = 2cm, auto]
        % Place nodes
        \node [cloud] (init) {Initialize};
        \node [block, left of = init, node distance = 4cm] (estimate) {Estimate};
        \node [block, below of = estimate, node distance = 3cm] (compute) {Compute};    
        \node [decision, below of = init] (decide_exploration) {$t \in (t_i, \, t_{i+1})$?};
        \node [decision, below of = decide_exploration, node distance = 4cm] (decide_sample) {$t_s \in (t_s^0, \, t_s^0 + T_s)$?};
        \node [block, right of = decide_sample, node distance = 4cm] (sample) {Sample};
        \node [block, below of = decide_sample, node distance = 4cm] (control) {Act};
        \node [below of = control, node distance = 2cm] (control2) {};
        \node [right of = control2, node distance = 6cm] (control3) {};
        \node [right of = decide_exploration, node distance = 2cm] (sample2) {};

        % Draw edges
        \path [line, dashed] (init) -- (estimate);
        \path [line] (estimate) -- (compute);
        \path [line] (compute) |- (control);
        \path [line] (decide_exploration) -- node {yes} (decide_sample);
        \path [line] (decide_exploration) -- node {no} (estimate);
        \path [line] (decide_sample) -- node {yes} (control);
        \path [line] (decide_sample) -- node {no} (sample);
        \path [line] (sample) |- (control);
                \path [line] (control) |-(6,-13) |-(sample2) |-(decide_exploration);

我对隐藏的节点使用了一些有趣的名称，您可能会发现一些更重要的东西。

编辑:我编辑了最后一行，因此角不再丢失。
