Struct SequencingWithDeadlinesAndSetUpTimes 

pub struct SequencingWithDeadlinesAndSetUpTimes { /* private fields */ }

Sequencing with Deadlines and Set-Up Times problem.

Given tasks with processing times l(t), deadlines d(t), compiler assignments k(t), and per-compiler setup times s(c), find a single-machine schedule in which all tasks meet their deadlines, where a setup penalty s(k(t')) is added before any task t that uses a different compiler than the immediately preceding task t'.

This is problem SS14 in Garey & Johnson (1979), written $1 | s_{ij} | \text{feasibility}$.

Configurations are direct permutation encodings with dims() = [n; n]: each position holds the index of the task scheduled at that position. A configuration is valid iff it is a permutation of 0..n.

Implementations

impl SequencingWithDeadlinesAndSetUpTimes

pub fn new( lengths: Vec<u64>, deadlines: Vec<u64>, compilers: Vec<usize>, setup_times: Vec<u64>, ) -> Self

Create a new sequencing instance.

Panics

Panics if the input vectors are inconsistent or contain invalid values.

pub fn num_tasks(&self) -> usize

Returns the number of tasks.

pub fn num_compilers(&self) -> usize

Returns the number of distinct compilers (= setup_times.len()).

pub fn lengths(&self) -> &[u64]

Returns the processing times.

pub fn deadlines(&self) -> &[u64]
