Toughest Sudoku Puzzles From A Mathematician

A.I. Generated Mind Bending Sudoku Puzzles

As we all know, Sudkoku is a logic-based, combinatorial number placement puzzle. The objective of this puzzle is to fill a 9x9 grid with digits wherein each column, each row  and each of nine 3x3 sub-grids that compose the grid contain all of the digits from 1 to 9. The puzzle creator provides a partially completed grid for us to complete the empty boxes. 

The Finnish Mathematician Arto Inkala built an algorithm to generate challenging Sudokus, called AI Sudoku. And, the two following puzzles are the most difficult one ever created by the bots.
