Struct AIPlayer 

pub struct AIPlayer { /* private fields */ }

An AI player that uses a solver to determine the best move to play in a Connect Four position.

The player’s skill level can be configured using the Difficulty enum, which adjusts the move selection strategy.

Implementations

impl AIPlayer

pub fn new(difficulty: Difficulty) -> AIPlayer

Creates a new AI player with a default solver and specified difficulty.

pub fn load_opening_book(&mut self, path: &Path) -> bool

Attempts to load an opening book from the given path for the AI player’s solver.

Returns whether the opening book was successfully loaded.

pub fn reset(&mut self)

Resets the AI player’s solver.

pub fn solve(&mut self, position: &Position) -> i8

Solves a position to find its exact score using the AI player’s solver.

pub fn get_all_move_scores(&mut self, position: &Position) -> [Option<i8>; 7]

Calculates the scores for all possible next moves in the given position using the AI player’s solver.

pub fn get_move(&mut self, position: &Position) -> Option<usize>

Solves and selects the AI player’s move for the given position.

pub fn select_move( &self, position: &Position, scores: &[Option<i8>; 7], ) -> Option<usize>

Selects a move from a fixed-size array of scores using a Softmax distribution with a temperature defined by the AI player’s difficulty. Temperature values <= 0 will result in greedy selection (always picking the best move).

Returns an Option<usize> containing the column index of the selected move, or None if no moves are possible.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
