The problem specification is given here.

Problem Specification:

For File Input Mode: (code: aicontest_file.py)

  • Participants will be given a assigned color('R'/'G') for the match through command line argument.
  • Participants will read from the file "shared_file.txt". The first line of the file declares the color of the player to make the current move. If the first line matches with the assigned color of the participant, they can make the move.
  • The following lines of the file will contain current condition of the grid. There will be 8 rows, each row has 8 strings. Each string indicates the current state of the corresponding cell in the grid. If the value of the string is “No”, then the grid is empty. Otherwise, it will contain 2 characters, first one denoting color of the orb (R/G), and 2nd one tells the number of orbs. Like, if “G2” is found on the 2nd string of 3rd row, that means cell [3, 2] contains 2 green balls.
  • To make the move participants will write '0' in the first line of the file "shared_file.txt". In the second line they will write x and y are coordinates for placing next orb in space separated manner.

Here is a state of the shared_file.txt after aicontest_file.py file has written to the R player:

R
No G1 No No R1 R1 G2 No 
No G1 R1 G1 R3 No R2 R2 
G1 R1 G1 G1 R1 G1 No No 
No G1 No R1 R1 No G1 No 
G1 No No No No G1 G2 R1 
R1 G1 R1 R1 G1 No R2 R1 
No R2 No G2 No R1 R1 No 
G1 G2 No G1 No G2 No No

For Console Input Mode: (code: aicontest.py)

  • Participants will receive “start” command from the console. (Can be read through scanf() or equivalent functions).

  • After that participants will receive the current situation of the grid from the console. There will be 8 rows, each row has 8 strings. Each string indicates the current state of the corresponding cell in the grid. If the value of the string is “No”, then the grid is empty. Otherwise, it will contain 2 characters, first one denoting color of the orb (R/G), and 2nd one tells the number of orbs. Like, if “G2” is found on the 2nd string of 3rd row, that means cell [3, 2] contains 2 green balls.

  • Participants can just print coordinates in console in a space separated manner ( In C, printf(“%d %d”, x, y) will work, where x and y are coordinates for placing next orb).

  • For console output mode participants need to change the following lines (line 327, line 329) in the aicontest.py to add the command to run their code accordingly.

Here,

p1 = subprocess.Popen(['python3', 'player_code.py', 'R'], stdout=subprocess.PIPE, stdin=subprocess.PIPE,
                          universal_newlines=True, bufsize=1)
p2 = subprocess.Popen(['python3', 'player_code.py', 'G'], stdout=subprocess.PIPE, stdin=subprocess.PIPE,
                          universal_newlines=True, bufsize=1)

For example if the participants writes code in C/C++ and generates output code named a.out the lines should be -

p1 = subprocess.Popen(['./a.out', 'R'], stdout=subprocess.PIPE, stdin=subprocess.PIPE,
                      universal_newlines=True, bufsize=1)
p2 = subprocess.Popen(['./a.out', 'G'], stdout=subprocess.PIPE, stdin=subprocess.PIPE,
                      universal_newlines=True, bufsize=1)
  • Participants can use any one of the above modes.
  • Participants need to make the move in reasonable amount of time.
  • Producing invalid move will disqualify the participant.
  • Participants must not make any other changes in the files aicontest.py or aicontest_file.py
  • Participants only need to write the player_code using the programming language of their preference.
  • Participants can look into the given sample player codes for further clarification.

Instruction for running:

  • Download the sample code from https://github.com/JakeShammo/CSE_Fest_AI_Contest repository
  • Run the aicontest.py/aicontest_file.py using python3 adding graphics speed as a command line argument. Here graphics speed denotes the speed of moves shown in the ui. You can try with different speed for your convenience. [ python3 aicontest.py 1000 ]. You may have to install package "numpy", "PyOpenGl" ( >=3.0), "Pygame" (>=1.9.0) to run this script (can be installed using pip) .
  • Run the player_code.py using python3 adding “R/G” as a commandline argument. [ python3 player_code.py R ]

Before running the aicontest.py or aicontest_file.py install required packages using: pip install -r Requirements.txt

For console input output mode run:

python aicontest.py 1000

For file input output mode run:

python aicontest_file.py 1000
python player_code_file.py R
python player_code_file.py G
