˚୨୧⋆ Simplex Solver ｡˚ ⋆

A simple implementation of a Simplex Tableau solver

✩ If you like this project, consider giving it a star! ✩

♡ What features does this have?

To keep it short - this has everything that this doesn't have (and more)!

• Editable matrix at any time by clicking the "Edit" button
• Resizable matrix which persists existing values when resized
• A (seperate) clear button to clear the entire matrix
• Manual pivoting by clicking a cell (0-cells can't be pivoted)
• Previous pivot states (you can unpivot until the initial tableau!)
• Automatic pivoting (a single time, useful for checking working)
• Solving and unsolving the whole Tableau in a single click
• Persistent state through localStorage (everything is saved)

Tip

You can hover over a button to get more information about it.

♡ Why does this exist?

I came across this recently, as I needed a basic solver for Simplex Tableau questions.

It's simple and allows for manual pivoting, which is exactly what I needed - except there were some issues:

• If I changed the dimensions of the tableau or reloaded the page, all of the values were cleared.
• If I pivot incorrectly, there's no undo or unpivot button. I have to completely refill the tableau.
• There's no button to automatically pivot once or to go back to the initial tableau.

Therefore, I decided to make my own implementation. This is "inspired" by the solver I referenced above, but no source code was used from it.

♡ Where do I find this?
