Struct TurnPlan 

pub struct TurnPlan<O, E> { /* private fields */ }

A computer player that plans its side’s turn on copies of the game: a beam search over its own commands (the module’s docs).

A decision does at most samples × candidates × (1 + width × (depth - 1)) units of work, a unit being one command applied to a copy.

Implementations

impl<O, E> TurnPlan<O, E>

pub fn new(order: O, eval: E, settings: PlanSettings, seed: u64) -> Self

A turn planner whose candidates come from order and whose partial turns are scored by eval, thinking as settings says. Its choices follow from seed.

pub fn settings(&self) -> PlanSettings

How it thinks.

pub fn search<R>(&mut self, rules: &R) -> PlanSearch<'_, R, O, E>

where R: Determinize, R::Command: Clone + PartialEq, O: Order<R>, E: Evaluate<R>,

Starts a decision in rules, which is not over: its first commands are listed, its seeds drawn and its copies made. PlanSearch::advance does the work.

Panics

If the game lists no legal command, or the order drops them all; with a message naming determinize when a copy lists other commands than the real state.

Trait Implementations

impl<R, O, E> Bot<R> for TurnPlan<O, E>

where R: Determinize, R::Command: Clone + PartialEq, O: Order<R>, E: Evaluate<R>,

fn choose(&mut self, rules: &R) -> R::Command

The first command of the best plan (or, at a temperature, one picked by the softmax).

Panics

As TurnPlan::search and PlanSearch::advance do.

impl<O: Clone, E: Clone> Clone for TurnPlan<O, E>

fn clone(&self) -> TurnPlan<O, E>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<O: Debug, E: Debug> Debug for TurnPlan<O, E>

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

Formats the value using the given formatter.
