Enhancing Sudoku Solver Algorithm Efficiency

Job ID: 37572087

Budget: €8 – €30 EUR

I'm in search of an expert developer who has proficiency in Python. The existing project involves a sudoku solving algorithm that I want refined to increase its efficiency.

The code currently is quite small, and will provide a .ipynb with all the instructions and test cells that will test the efficiency.

The code itself is mostly done, however there are some error which I cannot detect that are causing it to fail.
Please find the code attached below
