Struct vrp_core::algorithms::mdp::ActionEstimates

pub struct ActionEstimates<S: State> { /* fields omitted */ }

Keeps track of action estimation.

Implementations

impl<S: State> ActionEstimates<S>

pub fn insert(&mut self, action: <S as State>::Action, estimate: f64)

Sets estimate for given action. Min-Max values are not updated and require a recalculate_min_max call.

pub fn recalculate_min_max(&mut self)

Recalculates min max values.

pub fn weighted(&self, random: &(dyn Random + Send + Sync)) -> Option<S::Action>

Returns an action based on its estimate interpreted as weight.

pub fn random(&self, random: &(dyn Random + Send + Sync)) -> Option<S::Action>

Gets random action.

pub fn max_estimate(&self) -> Option<(<S as State>::Action, f64)>

Returns a max estimate.

pub fn min_estimate(&self) -> Option<(<S as State>::Action, f64)>

Returns a min estimate.

pub fn data(&self) -> &HashMap<S::Action, f64>

Returns actual action estimates data.
