Attempt at translating the Excel CLP Solver (original author Güneş Erdoğan)
Original file can be found at: https://people.bath.ac.uk/ge277/index.php/clp-spreadsheet-solver/
I extracted the two VB scripts and started the tedious process of translation to PHP.
Since I don't know any visual basic, I expect this to take a long time.
You might notice that most lines carry comments above. I use phpStorm and add docblocks along with the original VB code. e.g.
/** * Dim max_z As Double * @var float */ $max_z = 0.0;
The original code that's being translated in this example is
Dim max_z As Double
