设计一种能够预测碰撞的算法，使用 `tikzpicture` 环境选择替代路径

这是上一个问题的附录：如何使用环境pic通过一组彩色箭头连接tikzpicture。

我希望能够绘制不与节点和/或图片重叠的箭头，而不必手动修改与它们相撞的每一个箭头使用tikz。

平均能量损失

我们可以使用类似这样的路径来看到这些箭头：

我想要的是

可以看到，一些黄色，浅蓝色和蓝色箭头由于一个（或多个）的碰撞而发生了变化pic。

算法最好能够检测到，如果多种颜色在同一条路径上循环，则选择另一种颜色，因为在同一条路径中出现多种颜色会造成视觉混淆。例如：

我想要的例子

如果检测大量箭头交通是一个计算问题，那就不管它了，它不是很重要，我对自动路径就很满意了。

谢谢！！

答案1

这是第一个建议。你只需要说

\draw[-latex,blue,very thick] (4-Title.east) 
[along node/.list={12,21,29}]
        to[manoooh curve] (36-Title.west);

要得到

在此处输入图片描述

如您所见，该路径从12、21、形体以北延伸29。

至于您的循环：您可以在列表中指定路径应沿其运行的节点。
