Struct TrackAndStopBandit 

pub struct TrackAndStopBandit { /* private fields */ }

A multi-armed bandit using the Track-and-Stop algorithm for best-arm identification. Given a small set of pre-selected configurations, it adaptively allocates samples to identify the best one with statistical rigor.

Implementations

impl TrackAndStopBandit

pub fn new(arms: Vec<Configuration>) -> Self

pub fn n_arms(&self) -> usize

Number of arms.

pub fn is_stopped(&self) -> bool

Whether the bandit has stopped (declared a winner).

pub fn winner(&self) -> Option<usize>

The winning arm index (if stopped).

pub fn arm_config(&self, i: usize) -> Option<&Configuration>

Get the configuration for an arm.

pub fn ask(&self) -> Option<usize>

Which arm to sample next. Returns None if stopped.

pub fn tell(&mut self, arm: usize, reward: f64)

Report a reward for an arm.

pub fn arm_means(&self) -> Vec<f64>

Get the mean reward for each arm.
