Struct vrp_core::models::problem::Multi

pub struct Multi {
    pub jobs: Vec<Arc<Single>>,
    pub dimens: Dimensions,
    // some fields omitted
}

Represents a job which consists of multiple sub jobs. All of these jobs must be performed or none of them. Order can be controlled via specific dimension value.

Fields

jobs: Vec<Arc<Single>>

A list of jobs which must be performed.

dimens: Dimensions

Dimensions which contains extra work requirements.

Implementations

impl Multi

pub fn new(jobs: Vec<Arc<Single>>, dimens: Dimensions) -> Self

Creates a new multi job from given 'dimens' and jobs assuming that jobs has to be inserted in order they specified.

pub fn new_with_permutator(
    jobs: Vec<Arc<Single>>,
    dimens: Dimensions,
    permutator: Box<dyn JobPermutation + Send + Sync>
) -> Self

Creates a new multi job from given 'dimens' and jobs using permutator to control insertion order.

pub fn permutations(&self) -> Vec<Vec<Arc<Single>>>

Returns all sub-jobs permutations.

pub fn validate(&self, permutations: &[usize]) -> bool

Validates given set of permutations.

pub fn bind(multi: Self) -> Arc<Self>

Wraps given multi job into Arc adding reference to it from all sub-jobs.

pub fn roots(single: &Single) -> Option<Arc<Multi>>

Returns parent multi job for given sub-job.
