如何在 TikZ 中制作这样的流程图？

Question

我是 Latex 新手。有人能帮我在 TikZ 中绘制附图中的图表吗？

很抱歉没有添加 wml 包，但我尝试了 TikZ 包，但无法处理它。

以下是框内的文字：

holder receives n messages,
Exclusion test,
Connect them (Suspicious),
They are distinct,
Generate equation,
Eliminate Cliques,
A  group

这是一个建议。这当然不是最优雅的选择，但也许是学习这类东西最简单的方法。

\documentclass[tikz,border=3.14mm]{standalone}
\usetikzlibrary{positioning,shapes.geometric,shapes.misc}
\begin{document}
\begin{tikzpicture}
 \begin{scope}[every node/.append style={draw},cifi/.style={inner sep=1pt,circle,draw,fill=#1}]
  \node[rounded corners](A){holder receives $n$ messages};
  \node[diamond,below=1cm of A](B){Exclusion test};
  \node[rounded corners,align=center,below right=1cm and 2cm of B] (C) {Connect
  them\\ (Suspicious)};
  \node[rounded corners,below left=1cm and 2cm of B] (C') {They are distinct};
  \node[rounded corners,below=1cm of C] (D) {Generate equation};
  \node[rounded corners,below=1cm of D] (E) {Eliminate Cliques};
  \node[rounded corners,below=1cm of E] (F) {A  group};
  \node[cifi=white,right=3mm of C'] (S1) {$T_1$};
  \node[cross out,line width=1mm,red,right=3mm of S1] (X1) {};
  \node[cifi=white,right=3mm of X1] (S2) {$T_2$};
  \node[cifi=green,below=8mm of X1] (T1) {$T_1$};
  \node[cifi=green,right=4mm of T1,yshift=1mm] (T4) {$T_4$};
  \node[cifi=green,below right=3mm of T4] (T5) {$T_5$};
  \node[cifi=green,below left=3mm and 2mm of T5] (T7) {$T_7$};
  \node[cifi=orange!60,below left=4mm and 6mm of T4] (T3) {$T_3$};
  \node[cifi=orange!60,left=3mm of T3] (T2) {$T_2$};
  \node[cifi=orange!60,below right=3mm and 2mm of T2] (T6) {$T_6$};
  \node[cifi=orange!60,right=3mm of C] (T5') {$T_5$};
  \node[cifi=orange!60,right=3mm of T5'] (T3') {$T_3$};
 \end{scope}
 \begin{scope}[thick,>=latex,font=\small]
  \draw (T1) -- (T4) -- (T3) -- (T2) -- (T6) -- (T3) -- (T7)  (T5') -- (T3');
  \draw[->] (A) edge (B) (C) edge (D) (D) edge (E) (E) edge (F);
  \draw[->](B)  -| node[above,pos=0.2]{Negative}(C) ;
  \draw[->](B) -| node[above,pos=0.2]{Positive} (C');
 \end{scope}
 \draw[dashed] plot[smooth cycle] coordinates {([xshift=-3mm,yshift=1mm]T2.north west)
 ([xshift=2mm,yshift=1mm]T3.north east) ([yshift=-1mm,xshift=1mm]T6.south east)
 ([yshift=-1mm,xshift=-1mm]T6.south west)}; 
 \draw[thick,latex-] ([yshift=-1mm,xshift=-1mm]T6.south west) -- ++ (-1,-0.5) node[left] {a group};
\end{tikzpicture}
\end{document}
