The ach Solver will not take that into account.

What do I mean by local? It means that people base their next step on the number or candidate that they have found in the previous step. A human solver thinks and scans the board far more "human-like", which oftentimes is more chaotic, and also more local. The computer solver strictly tries one technique after another (and always does the same checks in the same order within that technique's execution). That is of course true, and yet there are still some differences between the two, mainly the following: We have said before that a computer solver tries to imitate a human solver. Where it is not perfect, though, is with imitating humans completely. It is perfect in the sense that it can spot everything that it should be able to spot. The computer Sudoku solver is not perfect That means that if the Solver shows you something advanced like Simple Coloring, then you know that it failed to find anything easier than this (and you could not either). We've already seen the ordering of the techniques on the page Sudoku Difficulty, so we already know in what order the Solver should execute the techniques.įor every step the Solver makes (for every click on the ' >' button) the techniques are tried in that order, and only if the Solver finds something for a technique, the step is completed and its result is shown to the user. We start to look for the easy stuff, and if we cannot find anything, we start to look for increasingly difficult things. (how likely it is that the technique will actually yield a result)Īfter all, this is how people do it. how difficult it is to apply the technique, and also.To imitate a human solver, we first need to order all techniques by It is always helpful, though, to see the Sudoku grid from different perspectives, and seeing the whole grid as cells with cell candidates in them, might give you a new perspective. Let me assure you, that you don't need those notations for using the basic techniques. It is only for consistency reasons that the computer solver notates cell candidates from the start. I thought, this solver should imitate humans? People don't do this." That is true, people generally start to write down cell candidates when only few candidates remain for a single cell, or when they are stuck and need to use more advanced techniques. "The solver uses so many pencil marks.It will be much quicker at applying those techniques, but it will not do anything impossible for you and me. If it is taught the techniques that people use, then it will do nothing more than what people do. A computer can only do, what it is taught. "Of course the computer can solve Sudokus easily, it's a computer, after all." Please don't see computers as magical machines that are not comparable to humans.There are two common responses that I get from people who don't have experience with computer solvers (or much experience with computers at all): If more than 15 business days have passed since we’ve approved your return, please contact us.Don't let this solver intimidate you.
