Struct BlindHeuristic 

pub struct BlindHeuristic;

A blind heuristic that returns 0 at the goal and 1 otherwise.

This is the simplest admissible heuristic, equivalent to treating the search as uniform-cost with goal checking.

Examples

use miniplan::heuristic::BlindHeuristic;
use miniplan::search::Heuristic;

assert_eq!(BlindHeuristic.name(), "blind");

Trait Implementations

impl Heuristic for BlindHeuristic

fn name(&self) -> &str

A human-readable name for this heuristic.

fn estimate(&self, task: &Task, state: &State) -> HValue

Estimate the cost from state to the goal in task.

fn preferred_ops(&self, _task: &Task, _state: &State) -> &[OpId]

Return preferred operators for the current state (used by some planners). The default implementation returns an empty slice.
