Breaking changes

The Tableau constructor now creates standard form LPs by default. The signature for Tableau is

function Tableau(A::AbstractMatrix, b::Vector, c::Vector, canonical::Bool=false)

Previously, the default for canonical was true. We switched to false because the Simplex Method works on tableaux in standard form. That means if the data is for a canonical form LP, it needs to be converted to standard form. Therefore standard form is more natural for the Simplex Method and we felt it should be the default for the Tableau constructor.

Summary

• If the LP is in standard form, minimize c'x s.t. Ax = b, x ≥ 0, use Tableau(A, b, c).

• If the LP is in canonical form, minimize c'x subject to Ax ≥ b, x ≥ 0, use Tableau(A, b, c, false).

Recommendation: add release notes

Release notes help your users know what has changed in the new version. For breaking releases in particular, it's recommended to document what breaking changes were made (or point to where changes can be found, such as a changelog).

To add release notes, just add markdown formatted text underneath the comment after the text "Release notes:" and it will be added to the registry PR, and if TagBot is installed it will also be added to the release that TagBot creates. i.e.

@JuliaRegistrator register

Tagging

After the above pull request is merged, it is recommended that a tag is created on this repository for the registered package version.

This will be done automatically if the Julia TagBot GitHub Action is installed, or can be done manually through the github interface, or via:

git tag -a v0.5.0 -m "<description of version>" 40c095b1290b0b392ae17f113758944ca837d20a
git push origin v0.5.0

Usage

• If the LP is in standard form, minimize c'x s.t. Ax = b, x ≥ 0, use Tableau(A, b, c).

• If the LP is in canonical form, minimize c'x subject to Ax ≥ b, x ≥ 0, use Tableau(A, b, c, false).
