Struct Solution

pub struct Solution {
    pub id: usize,
    pub layout_snapshots: Vec<LayoutSnapshot>,
    pub usage: fsize,
    pub placed_item_qtys: Vec<usize>,
    pub target_item_qtys: Vec<usize>,
    pub bin_qtys: Vec<usize>,
    pub time_stamp: Instant,
}

Represents a snapshot of a Problem at a specific moment. Solutions can be used to restore the state of a Problem to a previous state.

Fields

id: usize

Unique identifier for the solution

layout_snapshots: Vec<LayoutSnapshot>

Snapshots of all Layouts in the Problem at the moment the solution was created

usage: fsize

Average usage of bins in the solution

placed_item_qtys: Vec<usize>

Quantity of placed items for each Item in the solution

target_item_qtys: Vec<usize>

Target quantity of each Item in the solution

bin_qtys: Vec<usize>

Quantity of bins used for each type of bin

time_stamp: Instant

Instant the solution was created

Implementations

impl Solution

pub fn new( id: usize, layout_snapshots: Vec<LayoutSnapshot>, usage: fsize, placed_item_qtys: Vec<usize>, target_item_qtys: Vec<usize>, bin_qtys: Vec<usize>, ) -> Self

pub fn is_complete(&self, instance: &dyn InstanceGeneric) -> bool

Whether all items demanded in the instance are placed

pub fn completeness(&self, instance: &Instance) -> fsize

Ratio of included item area vs total demanded item area in the instance

pub fn missing_item_qtys(&self, instance: &Instance) -> Vec<isize>

Returns the quantities of the items that still need to be placed to reach a complete solution.

pub fn n_items_placed(&self) -> usize

Trait Implementations

impl Clone for Solution

fn clone(&self) -> Solution

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Solution

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

Formats the value using the given formatter.
