Java Sudoku Solver with Visualized Solution

Java Sudoku Solver with a UI that visually demonstrates the solving process using a holistic backtracking algorithm. The solver is designed to solve the hardest parts of the puzzle first before moving on to easier parts, resulting in faster solving times. Additionally, the solver uses multithreading to slow down the solving process, allowing the user to watch the solution unfold in real time. Whether you're a Sudoku enthusiast or simply interested in backtracking algorithms, this project showcases my skills in Java development and problem solving.
