final_step: usize

Implementations

impl EpsilonGreedy

pub fn new() -> Self

Constructs epsilon-greedy explorer.

pub fn with_final_step(final_step: usize) -> DqnExplorer

Constructs epsilon-greedy explorer.

TODO: improve interface.

pub fn action(&mut self, a: &Tensor) -> Tensor

Takes an action based on the observation and the critic.

pub fn action_with_best(&mut self, a: &Tensor) -> (Tensor, bool)

Takes an action based on the observation and the critic.

pub fn eps_final(self, v: f64) -> Self

Set the epsilon value at the final step.

pub fn eps_start(self, v: f64) -> Self

Set the epsilon value at the start.

Trait Implementations

impl Clone for EpsilonGreedy

fn clone(&self) -> EpsilonGreedy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EpsilonGreedy

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EpsilonGreedy

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for EpsilonGreedy

fn eq(&self, other: &EpsilonGreedy) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for EpsilonGreedy

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
