Struct RankedRootMove 

Source 
pub struct RankedRootMove {
    pub mv: Move,
    pub best_value: f64,
    pub mean_value: f64,
    pub win_probability: f64,
    pub leaf_count: usize,
    pub total_multiplicity: u64,
    pub has_terminal_win: bool,
}
Expand description

Aggregated beam-sampled statistics for one first move from the root.

These are optimistic, beam-sampled statistics computed over whichever leaves this particular engine run happened to discover and keep — they are not a minimax-proven guarantee. win_probability is a heuristic rescaling of mean_value into [0, 1], not a calibrated probability.

Fields§

§mv: Move§best_value: f64

Max leaf value via this move, root-player perspective.

§mean_value: f64

Multiplicity-weighted mean, root-player perspective.

§win_probability: f64

Heuristic rescaling: (mean_value + 1) / 2.

§leaf_count: usize

Number of collected leaves supporting this move.

§total_multiplicity: u64

Sum of multiplicity over supporting leaves.

§has_terminal_win: bool

A proven root-player-winning terminal exists via this move.
