Detailed Description

Sample AI thinker using a basic Minimax algorithm with a naive heuristic which previledges center board positions.

This is the same implementation used in the Implementing a simple Minimax player tutorial.

Member Function Documentation

◆ Setup()

override void Setup ( string str )

inlinevirtual

Setups up this thinker's maximum search depth.

Parameters

str	A string which should be convertible to a positive `int`.

If str is not convertible to a positive int, the maximum search depth is set to defaultMaxDepth.

See also: ColorShapeLinks.Common.AI.AbstractThinker.Setup

Reimplemented from AbstractThinker.

◆ Think()

override FutureMove Think	(	Board	board,
		CancellationToken	ct
	)

inlinevirtual

Perform a move.

Parameters

board	The game board.
ct	A cancellation token.

Returns: The move to be performed.

The main thread may ask the thinker to stop thinking. As such, this method should frequently test if a cancellation request was made to the cancellation token (ct ). If so, it should return immediately with no move performed, as exemplified in the following code:

if (ct.IsCancellationRequested) return FutureMove.NoMove;

See also: IThinker.Think

Implements AbstractThinker.

◆ ToString()

override string ToString ( )

inline

Returns the name of this AI thinker which will include the maximum search depth.

Returns: The name of this AI thinker.
