P Versus NP

Authors: Nikos Dimitris Fakotakis
Comments: 1 Page. P = NP

The generalized Sudoku problem, with S as the setof the symbols, is known to be NP-complete and it is equivalent to any other NP-complete problem. In this paper, we present a method that solves the Sudoku Problem in polynomial time and proves that P = NP.
