Picross Solver

Demo Video

• Black and White (B&W) Picross
• Color Picross

Requirement

• MATLAB2023a

How to execute

To execute the B&W Picross solver, you should change the workspace location to matlab/BnW_Picross/bnw_picross_solver and run main.m.

>> cd matlab/BnW_Picross/bnw_picross_solver

>> main

To execute the Color Picross solver, you should change the workspace location to matlab/Color_Picross/color_picross_solver and run main.m.

>> cd matlab/Color_Picross/color_picross_solver

>> main

Custom Picross

If you want to solve a custom puzzle using B&W Picross solver, first create a <location>/<name>.txt file in the following format. The keyword <location> represents the folder that puzzle data file is located, and <name> means the name of the data file.

n_row n_col

row_clue 1
...
row_clue n_row

col_clue 1
...
col_clue n_col

The parameters n_row and n_col mean the the number of rows and columns, respectively. The parameter row_clue i means the clue of i-th row, and col_clue i means the clue of i-th column.

Then substitute <location>/<name>.txt to the keyword argument file of the function Parameter.get_parameter in the file main.m

param = Parameter.get_parameter(file="<location>/<name>.txt")

Finally, execute main.m

>> main

If you want to solve a custom puzzle using Color Picross solver, first create a <location>/<name>.txt file in the following format. The keyword <location> represents the folder that puzzle data file is located, and <name> means the name of the data file.

n_row n_col n_color

color 1
...
color n_color

row_clue 1
...
row_clue n_row

col_clue 1
...
col_clue n_col

row_color 1
...
row_color n_row

col_color 1
...
col_color n_col

The parameter n_color represents the number of colors used in the picross. The parameter color i means the i-th color used in the picross. The parameters row_color i, col_color i represent the color indices response to row_clue i, col_clue i, respectively.
