Sudoku Plus Plus

A collection of Sudoku Solvers, attempting to increase the performance each time (while hopefully learning C++)

Implemented Solvers

1. Naive Backtracking

The first solver implements a basic backtracking technique, brute forcing the puzzle until the solution is found.

2. Backtracking with Bitset and Array (or BTBitset)

Spin-off of Naive Backtracking, this time using the std::bitset and C-style arrays to cut down on execution time.
