pub struct InsertionContext {
    pub problem: Arc<Problem>,
    pub solution: SolutionContext,
    pub environment: Arc<Environment>,
}

solution: SolutionContext

Solution context: discovered solution.

environment: Arc<Environment>

Information about environment.

Implementations

impl InsertionContext

pub fn new(problem: Arc<Problem>, environment: Arc<Environment>) -> Self

Creates insertion context for given problem with unassigned jobs.

pub fn new_empty(problem: Arc<Problem>, environment: Arc<Environment>) -> Self

pub fn new_from_solution(
    problem: Arc<Problem>,
    solution: (Solution, Option<Cost>),
    environment: Arc<Environment>
) -> Self

Creates insertion context from existing solution.

pub fn restore(&mut self)

Restores valid context state.

pub fn deep_copy(&self) -> Self
