Struct BeamSearchConfig 

pub struct BeamSearchConfig {
    pub beam_width: usize,
    pub max_depth: u32,
    pub rollouts_per_candidate: u32,
    pub random_seed: Option<u64>,
    pub beam_schedule: Option<Vec<usize>>,
    pub rollout_schedule: Option<Vec<u32>>,
    pub time_limit_s: Option<f64>,
}

Configuration for the beam search algorithm.

Fields

beam_width: usize

Frontier nodes kept per depth (>= 1).

max_depth: u32

Plies from root; 16 = full Quantik game. Must be 1..=16.

rollouts_per_candidate: u32

Rollout budget for the default evaluator (>= 1).

random_seed: Option<u64>

beam_schedule: Option<Vec<usize>>

Depth-dependent beam width: width at depth d = beam_schedule[min(d-1, len-1)], so the last entry extends to all deeper levels. None applies the flat beam_width everywhere.

rollout_schedule: Option<Vec<u32>>

Depth-dependent rollout budget for the BUILT-IN evaluator only — a custom evaluator keeps its plain signature and ignores this. Semantics mirror beam_schedule.

time_limit_s: Option<f64>

Optional wall-clock budget for search, in seconds. Checked between depth levels (after each completed level), so depth 1 always completes and a wide level can overshoot the budget — callers that need honest numbers should measure actual elapsed time themselves.

Trait Implementations

impl Clone for BeamSearchConfig

fn clone(&self) -> BeamSearchConfig

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BeamSearchConfig

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

Formats the value using the given formatter.

impl Default for BeamSearchConfig

fn default() -> Self

Returns the “default value” for a type.
