Minesweeper API summary

Here are the most important classes, fields and methods in the Minesweeper API. For more details, read the Javadoc and/or look at the source code.

All fields and methods are public unless noted otherwise.

enum ETile { MINE, FREE, UNKNOWN; }

class Tile

boolean visible;

ETile type; // if visible, type is MINE or FREE; if not visible, type is UNKNOWN

Integer mines; // number of surrounding mines; null if tile is not visible

boolean flag; // true if flagged by player

class Board

int width;

int height;

Tile[][] tiles;    // indexed as tiles[x][y]

int totalMines;  // total number of mines (visible + invisible) on the board

class Action

class ArtificialAgentActions

Action open(int tileX, int tileY)

Return an Action that uncovers the tile at (tileX, tileY). If this tile is a mine, your game is over!

Action flag(int tileX, int tileY)

Return an Action that marks the tile at (tileX, tileY) as a known mine.

Action advice()

Return an Action that asks for a hint.

abstract class ArtificialAgent

Implement your agent as a subclass of this class.

protected ArtificialAgentActions actions;

protected abstract Action thinkImpl(Board board, Board previousBoard)

The framework calls this method to ask for your next action.

On each call, board is the current board state and previousBoard is the board state from the previous call to this method. You can compare board and previousBoard to determine the new information that is available (e.g. as a consequence of opening a square on your previous turn).
