Chess Alpha Zero

This service uses Chess Alpha Zero to play chess with reinforcement learning by AlphaGo Zero methods.

It is part of our third party DNN Model Services.

Welcome

The service receives a chess move as input, like c2c4. This move means that the piece is at column c and row 2 and will move to the position at column c and row 4.

The model can detect illegal and end game moves.

What’s the point?

The service uses deep neural network and reinforcement learning techniques to play chess.

The service outputs the best move that the pre-trained model supply.

How does it work?

The board has this layout:

    a b c d e f g h
-------------------
8 | r n b q k b n r
7 | p p p p p p p p
6 | . . . . . . . .
5 | . . . . . . . .
4 | . . . . . . . .
3 | . . . . . . . .
2 | P P P P P P P P
1 | R N B Q K B N R

Uppercase letters are white pieces and lowercase are black.

Each letter represents the following pieces:

P|p: pawns
R|r: rooks
N|n: knights
B|b: bishops
Q|q: queens
K|k: kings

The user must provide the following inputs in order to play with the service:

Inputs:

  • uid: The user id to keep playing the same game (optional, if not set the service will generate a random UID and send it back).
  • move: <col_1><row_1><col_2><row_2>.
    • <col_1>: column where the piece is.
    • <row_1>: row where the piece is.
    • <col_2>: column where the piece will be moved to.
    • <row_2>: row where the piece will be moved to.
  • cmd: A specific command to interact with the service (optional).
    • "restart": restart the game, keeping the UID.
    • "finish": finish the game, deleting the UID.

You can use this service from SingularityNET DApp.

You can also call the service from SingularityNET CLI (snet).

Assuming that you have an open channel to this service:

$ snet client call snet zeta36-chess-alpha-zero default_group play '{"uid": "my_uid","move": "c2c4"}'

response:
UID: my_uid
