我使用以下代码绘制了左侧描述的流程图...但是，我想按照左侧描述的方式进行绘制。我想将箭头向左/向右移动，而不是在 L - BFGS 框的中心移动。
你好，我想制作一个如上图右侧所示的流程图。例如，一个箭头从 L BFGS 向下指向 AKR & Gradient，然后另一个箭头从 AKR 向上指向 L BFGS。向下的箭头位于矩形的左侧，而向上的箭头位于矩形的右侧。
关于我分享的代码，我该如何编辑它？
代码如下：

\usepackage[utf8]{inputenc}
\usepackage{tikz}
\usetikzlibrary{shapes.geometric, arrows}
\tikzstyle{startstop} = [rectangle, rounded corners,

minimum height=0.9cm,
text centered,
draw=black,

\tikzstyle{second} = [rectangle, rounded corners,
