您的项目看起来很酷,所以我花了一些时间寻找解决方案。我想出了下面的代码。代码的结果是:
OUTPUT[XNOR[NOR[AND[B, A], OR[D, C]], XOR[NOT[G], NAND[E, F]]]]
我假设如果一个元素比另一个元素在最左边,那么它就是前一个块。我还假设在您的一组行中,第一行是正确的...这使我可以将您的 14 组几行简化为一组 14 行。

如果需要,我可以改天再解释,或者您可以从这里开始。无论如何,尽情享受您的项目吧。
编辑:
我的目标是构建一个图,其中节点是框,边是线。问题是这些线仅被定义为一组闭合线。他们也处于混乱状态,但首先。所以第一步就是把每组线变成一条直线。这就是我所说的sorted_lines。
为了构建这个列表,我使用了以下逻辑:
- 对于每组线,将其分为连接部分和非连接部分
- 连接部分的初始化是集合的第一行。正如我所说,在这里我假设第一行是正确的。尝试改进这一点,因为这种假设在其他情况下可能是错误的。
-
当有非连接线时,请执行以下操作:
- 找到距离连接部分最近的段
- 将其从非连接部分移除
- 检查段的哪一端离连接部分最近
- 如果它是线段的第一个点,则连接部分的最后一个点将成为线段的第二个点,否则第一个点将成为最后一个点。
在检查中,未处理的情况是当要连接的段关闭到连接部分的第一个点而不是最后一个点时。这没有处理,因为我假设第一行是正确的。再一次,这可以改进。
现在你已经对你的行进行了排序,为每一行找到包含每一端的节点。选择最左边的作为源门,选择最右边的作为目的门。由于边缘没有方向,我不得不假设一个方向。更新目的门的输入和源门的输出。
最后打印图表的最后一个门。
