When you hear the Word Puzzle, What is the first thing that comes into your mind? There are so many words that could jumble in your mind, it could be a problem, a riddle, a question a mystery and much more. However, can you not realize that the bottom line for each puzzle is to find a solution?
It's the same thing with Sudoku puzzle. Firstly, it is important that you need to learn about the basic rules and instructions on this play. Secondly, you should learn to build your own strategy to win and finally reach a certain goal.
After being able to know the history and the factors included in the game, you will now reach a very important aspect is the method of solution. In Sudoku, there are actually three processes that are combined to solve the problem given to you.
aec Scanning
This is done at the beginning and during the execution of the solution. This can be done in the period between the analysis. It has two techniques namely the Cross-hatching, which involves the process of eliminating numbers of rows or columns. Second is the method of counting. This is used to identify missing numbers that will help accelerate your research. A player usually explores all possible contingencies during the scanning process.
aec Marking
The following ends when scanning. This is when the player could not find a better figure that can be discovered. It is the turning point of your logic analyzer. It is helpful if you can use some notation that will be placed on the empty cell for your advice. Your credit rating may be represented either by an index or a point. It depends on your preferences.
aec Analysis
Now is the last step you have to do. There are two main approaches, eliminating so-called candidates "and what-ifs. On the first approach, progress is sequentially remove candidate numbers to the point that there will only one choice to be left. For every solution achieved, another scan can be done. Several methods of candidate elimination can also be applied, it may be through matching of the cells or the corresponding numbers.
The "what if" approach somehow include guessing, although you'll still need to follow your logical choice of number. A cell that has only two digits candidate is selected, then you can make your own proposal.
In an IT solution, it also uses a different approach so that the algorithm is commonly used. However, other more effective approaches have generally been found. It is the solution Sudoku programs such as:
aec The emulation of the solving methodology of man as closely as possible. This will allow the determination of the level of difficulty of the puzzle seizures.
aec It should have the ability to solve the particular problem in a puzzle as efficiently as possible. In this way, man can create a station for faster computing.
It is a fact that it is possible for computers to find a solution to the problem of the puzzle as fast as you want. However, you must also be able to determine if the method used by the computer is valid or not. In other words, there should be only one correct solution for every problem. Some of the computer analysis could even imitate a human solver, such as the approach of marking up. Rapid solvers can use both the trial and the process of the method so they can create the best possible solution to the problem.
In Sudoku puzzle, it is also ironic in contrast to other types of puzzle games. The lower of which are digital data is easier to solve while the more and more difficult given mean. Thus, the level of difficulty is not measured the amount of data, but the number wi.
