If generators already exist that cannot be distinguished from hand-made puzzles, I'd still have to test its efficacy somehow, or find a very convincing paper that shows how they built it, tested and proved that it is undistinguishable. That's why I want them, to have as a dataset.
SUDOKU COACH GENERATOR
Build an algorithm to identify characteristics that exist in human-made puzzles, and build a sudoku generator that meets all these characteristics.

SUDOKU COACH HOW TO
So the idea is, the best way to figure out how to make a good generator is to study how real puzzles are made, to analyze human-made puzzles. CLAUDETTE CHENEVERT, aka The Stepmom Coach, works with women as they struggle to create a cohesive family life. I'm not experienced at Sudoku (I struggle to even notice naked singles unaided until they're more obvious - I prefer not to use pencil marks if I can avoid it), so I don't know all the subtleties. I noticed that what it was doing was sometimes making diabolical puzzles, and sometimes too easy. I made a few experimental generators designed to be fast, but I have no control over difficulty. Ultimately, what I'm trying to do, is make a good, fast generator. Or maybe just manually added a few extra clues so something hard and see if it makes it easier.
sudoku.one was caught doing this for evil lvl. Sudoku Coach Lite helps you master 10 strategies among the easiest to learn and to use. What makes you belive a player didn't take an already generated grid and simply applied one or more of 2(6 8) transformations and claim its manual. This happens even with mine thats logic solved based. Since its random the puzzles difficult is random with a vast majority of generated grids are usually all singles. The NYT puzzles are all designed to only require the techniques called Basics, namely Singles, Box/Line Reductions (pointing/claiming digits in boxes) and Subsets.
After that there are three more difficulty levels.
SUDOKU COACH MANUAL
Ps guess what happens to manual and automation You can try and see if you like my website: NYT hard puzzles would be what is 'Very hard' on ach. This method is exponentially slower when more and more logic is used per step. fill all the empty cells with numbers between 1 and 9, so that no number. The grid can be divided into rows, columns and boxes of 3x3 cells (which are also called blocks). Hundreds of generators that do this top down,Īnd thousands of bad ones that don't do the last note.īottom up, random insertion with pure logic applied befor the next generator cycle adds a clue from reduced possibleįollowed by minimal reduction checks (clues that can be removed and still has 1 solution) It consists of 9x9 cells, and it contains some numbers between 1 and 9. You can solve puzzles yourself or you can request Sudoku Coach Lite to give you a hint or to suggest you the next action or to solve the puzzle step by step, with graphics and text explanations about each applied strategy.
Set à specific depth hierarchy, Guarenteeded to contain specific technique. Sudoku Coach Lite helps you master 10 strategies among the easiest to learn and to use. Want the clues symtrical, asymmetrical, non minimal So this special case probably never crossed the programmers mind, and also not the question whether it made sense to combine candidates of (in its eyes) different URs that share the same cells.What makes makes you belive a human isn't using dancing links ( algorithm x, brute force checker) to verify the random digits they plug into a blank grid or remove from a solution grid is guaranteed unique.Įverything à manual player accomplishes to build a grid is replicatable with automation there is no tanggable difference. A conscious decision about one rare type of a technique that is even disliked by some people. The programmer could have, of course, implemented the function so that it checks both at the same time, but that would have to be a conscious decision.
SUDOKU COACH PSP
Download Sudoku Coach emulator game and play the PSP ROM free. The past one had it's main cells on the right, the current one has its main cells on the left. Sudoku Coach ROM download available for Playstation Portable. The main loop then starts again, and if still no easier techniques can be found, it will call the UR function again and that one will then find the 8 on the left because it will look at a (in its eyes) different UR. If it does, it spits out the result (in this case the 8 on the right). Usually you would define a function for each technique and then loop over them one by one from easiest to hardest until one of those functions finds something. Well, it is an arbitrary decision how atomic you want your algorithms to be or how atomic you program them.
