Samurai Sudoku Solver

Some time ago, I got curious about building a "Sudoku Solver". At some point during my research, I had been experimenting with the Gurobi Optimizer to solve some problems I was facing. Some time later, I found PuLP, an open source solver for Linear Programs (LP), which allows for an easy solution to define and solve LP problems. Its tutorials include one in which a Sudoku Solver is built. By the time I learned about it, I had already built mine, and had already seen some other solvers, both downloadable and online. But I still have not seen any solvers for "Samurai Sudokus", so I built mine. And now, I have put it online.

If you want to try it, it is very easy: just put in the clues you have and press the "Solve" button. Please, be patient: this site is hosted on a SbC, and, as it is not very powerful, it may take up to 30 seconds to solve your Samurai Sudoku.
