Usage

1. Edit the generateRules.ts file to include the fixed numbers of the sudoku you want to solve

4. Run pnpm run visualize to convert the solution of the SAT solver within a result.cnf file back into a readable sudoku.

SAT Solver

I used the SAT solver CryptoMiniSat for this project, but other ones should be fine as well as long as they can handle DIMACS CNF files.
