We find that while the modified search procedure produces solutions more quickly, that it suffers the same issue that the original method has in that it sometimes fails to find a feasible solution. Each row, column and square (9 spaces each) needs to be filled out with the numbers 1-9, without repeating any numbers within the row, column or square. Within the rows and columns are 9 squares (made up of 3 x 3 spaces). Sudoku is played on a grid of 9 x 9 spaces. Then extended experiments were performed for various Sudoku problems. How to Play Sudoku Sudoku Rule 1: Use Numbers 1-9. For a specific problem, the modified version of harmony search generates a unique solution with new objective function in favorable time. Second, the modified version of the harmony search, where harmony search is combined with local search is introduced and analyzed for its contribution of ‘improvisation’ in harmony search procedure by comparing the performance of local search and the modified search. This proposed objective function facilitates the search method to find a proper solution. This isn’t an article about generating correct Sudoku matrices The second thing is to empty some cells in order to let the player play. First, we propose a new objective function for the search procedure. In this example, the most simple way to get a Sudoku matrix is to start with a default one. We found that the while the criticisms of the method for this problem are valid, that the performance can be improved with a rather simple modification. The basic harmony search procedure is re-implemented and tested to evaluate its performance and verify its applicability to the specific example. Our paper analyzes the search process in harmony search when applied to a specific Sudoku puzzle examined in earlier research. Another paper claims that it is ineffective for solving Sudoku puzzles and further that the method itself lacks novelty compared to other evolutionary algorithms. Several papers examined its effectiveness for solving Sudoku puzzles. The Harmony Search metaheuristic has been used to solve many different optimization problems.
