Required Methods§

source

fn action(&self) -> usize

The action chosen by the Agent.

source

fn arms(&self) -> usize

The number of arms in the Bandit the Agent is playing.

source

fn current_estimate(&self, arm: usize) -> f64

The Agent’s current estimate of the value of a Bandit’s arm.

source

fn reset(&mut self, q_init: &[f64])

source

fn step(&mut self, arm: usize, reward: T)
