Gomoku is a relatively simple board game. Its instrument is universal with Go, and it originated from one of the ancient Chinese black and white chess. Usually, the two sides use black and white chess pieces respectively, and at the intersection of the straight line and the horizontal line of the board, the next step is to form a five-member line to win.
In this assignment, we use the default board of size 15*15 board (administrators can modify the settings as needed). Students need to implement the AI algorithm of Gomoku according to the interface requirements and submit it to the system as required.
2 Evaluation Rule
The assessment is divided into 2 phases:
Usability testing: In this test, we will use some simple board test cases where students need to find the best place to drop. Only jobs that pass the usability test can pass.
Scoring stage: Students who pass the usability test can participate in the points game (积分赛). The specific competition rules are as follows: Students can submit their AI algorithm to the Gomoku battle platform (it is a successful submission if it passes the usability test). After a successful submission, select the player PK who ranks ahead of itself. The score is increased by 10 if it wins. The score remains unchanged if it is a tie. The score is reduced by 10 points if it loses. To avoid the first-hand advantage, each time the student should play against PK 2 innings with each one staring the game first. If they win twice, or win once and draw once, they win; if they win once and lose once, they draw; if they lose twice, or lose once and draw once, they lose.
The final score is given according to the points.
The following game gives an example of the battle between two AI algorithms. Of course, this example is very simple and is the simulation result of two random AI algorithms.
The score list is as follows
The Gomoku battle platform is still in the phase of developing internal tests, and there is still much room for improvement in all aspects. After the system is stable, we will open it to all students. At present, we are recruiting outstanding students to participate in development and testing.
