问题描述

我要生成一个迷宫,看起来像这样:

I want to generate a maze that looks like this:

也就是说,它是由三个随后连接在一个方向上的路径。我已经找了一个算法生成迷宫像这样没有成功。

That is, it consists of paths in one direction that are then connected. I have looked for an algorithm to generate mazes like this without success.

具体而言,我不要想这样的迷宫:

Specifically, I don't want a maze like this:

,因为它不仅在一个方向跑。

because it doesn't "run" in only one direction.

此外,这将是很好,如果这个迷宫的解决方案所需的球员原路返回 - 即不是所有的时间只是向上移动

Also, it would be nice if the solution of this maze required the player to "backtrack" -- i.e. not just move upwards all the time.

嗯,这很有趣!完成与ASCII艺术输出I present ...

Well that was fun! Complete with ASCII art output I present ...
