Random Maze Generator

Maze

This is a command-line Java application to generate random mazes.

How Does It Work?

1. An n x m matrix is generated, which contains n x m cells. Initially, each cell is generated with four walls surrounding it.
2. All of the cells are dumped into a union-find data structure. Cells are disjoint when there are no paths connecting them. In other words, exist walls that them off from each other.
3. Random walls are then processed.

• If there exists a path from the cell on one side of the wall to the cell on the other side of the wall, do nothing.
• Otherwise, remove the wall between those two cells and union the cells in the union-find data structure.

4. Repeat Step 3 until there are no disjoint sets in the union-find data structure. At that point, every cell will be reachable from any other cell in the maze.

Usage

To use this application:

1. Clone this repository using git clone https://github.com/hughhan1/Maze.git.
2. Compile the source code using javac *.java.
3. Run java MazeDriver <rows> <cols>, where and are the number of rows and columns of your maze.

Example:

$ cd ~/Desktop
$ git clone https://github.com/hughhan1/Maze.git
$ javac *.java
$ java MazeDriver 15 20

This will generate a random 15 x 20 maze, with 15 rows and 20 columns.
