Crate ratel_bandit

Ratel

A library for running multi-armed bandit simulations.

The simulation has two components: a Bandit with some number of arms which each has a payout according to some distribution, and an Agent that uses some strategy to learn the optimal bandit arm. A Game then consists of an Agent learning about a Bandit by pulling arms according to its preferred strategy.

Structs

• BinomialBandit
  A bandit whose arms distribute rewards according to the binomial distributions.
• EpsilonGreedyAgent
  Agent that follows the Epsilon-Greedy Algorithm.
• ExponentialBandit
  A bandit whose arms distribute rewards according to the exponential distributions.
• Game
  Structure to make the Agent interact with the Bandit.
• GammaBandit
  A bandit whose arms distribute rewards according to the gamma distributions.
• GaussianBandit
  A bandit whose arms distribute rewards according to the Gaussian distributions.
• GreedyAgent
  Agent that follows the Greedy Algorithm.
• HarmonicStepper
  Stepper with a harmonically decreasing step size.
• LogNormalBandit
  A bandit whose arms distribute rewards according to the Log Normal distributions.
• OptimisticAgent
  Agent that follows the Optimistic Algorithm.
• RecordCounter
  Counter for cases where individual records must be maintained.

Traits

• Agent
  A trait for common members of the Agents.
• Bandit
  A trait for common members of the Bandits
• Counter
  A trait for common methods required by all counters.
• Stepper
  Trait containing all methods required by all steppers.

Functions

• print_hms
  Prints the amount of time that has elapsed since a timer was started.
