Nettetclues. For example the Sudoku in Figure 1, the size of A is 341×729 and hence the linear system of equations (6) is underdetermined and has an infinite number of solutions. However, not every solution of (6) is a valid solution of Sudoku puzzle. Babu et al.[5] proved if the Sudoku puzzle has a unique solution, then the most sparsity solution Nettettechniques for solving Sudoku puzzles based on sparse optimization methods. The idea is to delete repeated numbers in the Sudoku solution, and then solve it again. Our …

The null space, Z, is a set of basis vectors spanning a subspace of A such that A·Z = 0. In other words, the columns of Z are vectors that are orthogonal to all of the rows in A. This means that for any solution x' to A·x = b, then x' …
