Maze (Greek: λ α β? ρινθο? Latin transliteration: labyrinthos) refers to a building, which is full of complicated passages, and it is difficult to find the road from its interior to the entrance or from the entrance to the center. The road is complex and difficult to distinguish, and it is difficult for people to get in and out. It is usually used to describe a complex and difficult problem or an elusive situation.
A single maze is a maze with only one way to go. For a single maze, there is a universal solution, which is to walk along a certain wall. When walking, the left (right) hand keeps touching the wall on the left (right) side. This method may take the longest time, or it may take you to every corner of the maze and every dead end, but players will never be trapped inside.
A complex maze is a maze with many moves. Because there are many ways to go, there must be some places in the complicated maze where you can go back to the original point without looking back. This passage can go back to the original point, showing a closed loop in the maze. With this ring as the boundary, the maze can be divided into several parts. Therefore, a complex maze is essentially composed of several single mazes.
For a complex maze, the above-mentioned "universal" cracking method may not be applicable, provided that the starting point and the ending point are in the same part of the complex maze. Although there are many ways to walk in a complicated maze, it is likely to be more complicated, because in a maze, going around in circles is worse than walking into a dead end.
