Swift Sudoku Solver
- MekaiGS 9y agoAs the author mentioned, it cannot solve any boards where all unfilled cells have more than one possible value within the cell's domain. More information about the algorithm here: https://en.wikipedia.org/wiki/AC-3_algorithm https://en.wikipedia.org/wiki/AC-3_algorithm You would need to implement something like forward checking or backtracking algorithm to solve all possible boards with higher cost.
- i_s 9y agoHere is one in Swift I did a few years ago that does: https://github.com/isaksky/sudoku-swift/blob/master/Sudoku-Swift/main.swift https://github.com/isaksky/sudoku-swift/blob/master/Sudoku-S... This one solves all 50 from Euler: https://projecteuler.net/problem=96 https://projecteuler.net/problem=96 And here is a classic one in Python from Norvig: http://norvig.com/sudoku.html http://norvig.com/sudoku.html

- mmanfrin 9y agoSo this can't solve anything more than the most trivial boards? :/
