我怎样才能将这个 tikzpicture 调整到适合我的 a4 页面？

我如何调整此 tikzpicture 以适应我的 a4 页面？我将其写在段落之后。但它位于标题之前，位于页面顶部。

                    \node[anchor=north east] at (A.north west) (a2) {$(\mathsf{com},\mathsf{dec}) \gets \mathsf{Com}(a)$};

对图形使用一些位置说明符。例如，请参阅此处的详细答案：如何影响 LaTeX 中图形和表格等浮动环境的位置？ 或者这里：[t] 和 [ht] 是什么意思？

如果您只是删除figure环境，您将无法添加标题和标签。在您的 MWE 中，我添加了位置[ht]，它将尝试将图形放在插入点或下一页的顶部。
