Struct Optimizer 

pub struct Optimizer { /* private fields */ }

Optimizer for optimizing rectangular cut pieces from rectangular stock pieces.

Implementations

impl Optimizer

pub fn new() -> Self

Create a new optimizer.

pub fn add_stock_piece(&mut self, stock_piece: StockPiece) -> &mut Self

Add a stock piece that the optimizer can use to optimize cut pieces. If the same stock piece is added multiple times, the quantities will be summed up. If any have a None quantity, the quantity on other equivalent pieces will be ignored.

pub fn add_stock_pieces<I>(&mut self, stock_pieces: I) -> &mut Self

where I: IntoIterator<Item = StockPiece>,

Add a stock pieces that the optimizer can use to optimize cut pieces. If the same stock piece is added multiple times, the quantities will be summed up. If any have a None quantity, the quantity on other equivalent pieces will be ignored.

pub fn add_cut_piece(&mut self, cut_piece: CutPiece) -> &mut Self

Add a desired cut piece that you need cut from a stock piece.

pub fn add_cut_pieces<I>(&mut self, cut_pieces: I) -> &mut Self

where I: IntoIterator<Item = CutPiece>,

Add desired cut pieces that you need cut from a stock piece.

pub fn set_cut_width(&mut self, cut_width: usize) -> &mut Self

Set the width of the cut to use between cut pieces. This could represent blade or kerf thickness.

pub fn set_random_seed(&mut self, seed: u64) -> &mut Self

Set the random seed used by the genetic algorithms in the optimizer. Using the same random seed will give you the same result for the same input.

pub fn allow_mixed_stock_sizes(&mut self, allow: bool) -> &mut Self

Set whether the optimizer should allow mixed sized stock pieces in the results. If set to false, and multiple stock sizes are given, only one stock size will be used in the results.

pub fn optimize_guillotine<F>( &self, progress_callback: F, ) -> Result<Solution, Error>

where F: Fn(f64),

Optimize in a way where each cut piece can be cut out using only guillotine cuts, where each cut extends from one side to the other.

This method is suitable for cutting with a panel saw.

pub fn optimize_nested<F>( &self, progress_callback: F, ) -> Result<Solution, Error>

where F: Fn(f64),

Optimize without the requirement of guillotine cuts. Cuts can start and stop in the middle of the stock piece.

This method is suitable for cutting on a CNC.

Trait Implementations

impl Default for Optimizer

fn default() -> Self

Returns the “default value” for a type.
