evaluation_parameters: Arc<EvaluationParameters>

Implementations

impl SEEContainer

pub fn new(evaluation_parameters: Option<Arc<EvaluationParameters>>) -> Self

Constructs a default instance of SEEContainer with zeroed elements.

pub fn get( &self, attacking_piece: usize, target_piece: usize, attackers: usize, defenders: usize ) -> i16

Gets a result of the static exchange evaluation, based on attacking_piece, target_piece, attackers and defenders.

fn evaluate( &self, target_piece: usize, attackers: usize, defenders: usize ) -> i16

Evaluates a static exchange evaluation result, based on target_piece, attackers, defenders.

fn evaluate_internal( &self, attacking_piece: usize, target_piece: usize, attackers: usize, defenders: usize ) -> i16

Recursive function called by evaluate to help evaluate a static exchange evaluation result.

fn get_see_piece_index(&self, piece: usize) -> usize

Converts piece index to SEE piece index, which supports multiple pieces of the same type stored in one variable:

• 1 pawn (index 0)
• 3 knights/bishops (index 1-3)
• 2 rooks (index 4-5)
• 1 queen (index 6)
• 1 king (index 7)

fn get_piece_value(&self, piece_index: usize) -> i16

Gets a piece value based on piece_index saved in SEE format (look get_see_piece_index).
