amazeR (a maze R)

mazeR.R

• mazeR.R has the original script in https://github.com/matfmc/mazegenerator.
• It has been modified to make the maze narrower.

generate_results_doSNOW.R

• Purpose: To simulate a player's random step in the maze.

Objects of interest

• N: Total number of simulations.
• xx e yy: Board size.
• ini: Initial game conditions (simple random sampling without replacement).
• first_plot: Starting plot of the board.
• results: Outputs of the simulations already organized to be used in Machine Learning.
• game: Conditions played.

Game example

• Red: Player's position.
• Green: Entrance to the maze.
• Blue: Exit the maze.

Output example

amazeR_functions.R

Functions:

get_game(nb, input, exit, position)

• Purpose: To create the maze by adding input, output and position of the player.
• nb: Simplified maze board.
• input: Coordinate of entrance of the labyrinth.
• exit: Coordinate of exit from the labyrinth.
• position: Character's current position.
• Inside get_game() has fobj(), an objective function, which scores the reward.

get_result_state(results)

• Purpose: To organize game information.
• results: Collection of some matches for the same board.

plot_maze(board_cells, input, exit, boxes)

• Purpose: Plot the game using ggplot. In the generated graph the lines are in reverse coordinate of the board. X axis represents columns and y axis lines.
• board_cells: Board generated by mazeR.R.
• entrance: Coordinate of entrance of the labyrinth.
• exit: Coordinate of exit from the labyrinth.
• boxes: Matrix containing valid coordinates in random walk.

plot_update(first_plot, position)

• Purpose: Update the player's position on the graph.
• first_plot: Object that stores the first plot_maze().
• position: Player's current position.

get_pos(position)

• Purpose: Returns the current position.

get_moves(position, nb)

• Purpose: Given the current position, return the possible movements.
• position: Character's current position.
• nb: Simplified maze board.

nb_update(nb, input, exit, position)

• Purpose: Update the player's position on the board.
• nb: Simplified maze board.
• input: Coordinate of entrance of the labyrinth.
• exit: Coordinate of exit from the labyrinth.
• position: Character's current position.
