In other words, you can turn a quadratic time complexity -(which is often too expensive) into linear time complexity. - -Finding optimal line breaks in a paragraph of text is an example of an algorithm -which would normally take O(_n_²) time for _n_ words. With this crate, the -running time becomes linear. Please see the [textwrap crate][textwrap] for an -example of this. - -## Usage - -Add this to your `Cargo.toml`: - -```toml -[dependencies] -smawk = "0.3" -``` - -You can now efficiently find row and column minima. Here is an example where we -find the column minima: - -```rust -use smawk::Matrix; - -let matrix = vec![ - vec![3, 2, 4, 5, 6], - vec![2, 1, 3, 3, 4], - vec![2, 1, 3, 3, 4], - vec![3, 2, 4, 3, 4], - vec![4, 3, 2, 1, 1], -]; -let minima = vec![1, 1, 4, 4, 4]; -assert_eq!(smawk::column_minima(&matrix), minima); -``` - -The `minima` vector gives the index of the minimum value per column, so -`minima[0] == 1` since the minimum value in the first column is 2 (row 1). Note -that the smallest row index is returned. - -### Cargo Features - -This crate has an optional dependency on the -[`ndarray` crate](https://docs.rs/ndarray/), which provides an efficient matrix -implementation. Enable the `ndarray` Cargo feature to use it. - -## Documentation - -**[API documentation][api-docs]** - -## Changelog - -### Version 0.3.2 (2023-09-17) - -This release adds more documentation and renames the top-level SMAWK functions. -The old names have been kept for now to ensure backwards compatibility, but they -will be removed in a future release. - -- [#65](https://github.com/mgeisler/smawk/pull/65): Forbid the use of unsafe - code. -- [#69](https://github.com/mgeisler/smawk/pull/69): Migrate to the Rust 2021 - edition. -- [#73](https://github.com/mgeisler/smawk/pull/73): Add examples to all - functions. -- [#74](https://github.com/mgeisler/smawk/pull/74): Add “mathematics” as a crate - category. -- [#75](https://github.com/mgeisler/smawk/pull/75): Remove `smawk_` prefix from - optimized functions. - -### Version 0.3.1 (2021-01-30) - -This release relaxes the bounds on the `smawk_row_minima`, -`smawk_column_minima`, and `online_column_minima` functions so that they work on -matrices containing floating point numbers. - -- [#55](https://github.com/mgeisler/smawk/pull/55): Relax bounds to `PartialOrd` - instead of `Ord`. -- [#56](https://github.com/mgeisler/smawk/pull/56): Update dependencies to their - latest versions. -- [#59](https://github.com/mgeisler/smawk/pull/59): Give an example of what - SMAWK does in the README. - -### Version 0.3.0 (2020-09-02) - -This release slims down the crate significantly by making `ndarray` an optional -dependency. - -- [#45](https://github.com/mgeisler/smawk/pull/45): Move non-SMAWK code and unit - tests out of lib and into separate modules. -- [#46](https://github.com/mgeisler/smawk/pull/46): Switch `smawk_row_minima` - and `smawk_column_minima` functions to a new `Matrix` trait. -- [#47](https://github.com/mgeisler/smawk/pull/47): Make the dependency on the - `ndarray` crate optional. -- [#48](https://github.com/mgeisler/smawk/pull/48): Let `is_monge` take a - `Matrix` argument instead of `ndarray::Array2`. -- [#50](https://github.com/mgeisler/smawk/pull/50): Remove mandatory - dependencies on `rand` and `num-traits` crates. - -### Version 0.2.0 (2020-07-29) - -This release updates the code to Rust 2018. - -- [#18](https://github.com/mgeisler/smawk/pull/18): Make `online_column_minima` - generic in matrix type. -- [#23](https://github.com/mgeisler/smawk/pull/23): Switch to the - [Rust 2018][rust-2018] edition.
