We see that has only one value and thus the can be removed from its peer all other peers giving . But the main message is that mean and median stay about same even as we sample more maximum keeps going up dramatically. Now that we have squares units and peers the next step is to define Sudoku playing grid. This licensing tag was added to file part of the GFDL update tp licenses bysa. If instead we chose G which only has possibilities expect to be wrong with probability . My algorithm for making random puzzle is simple first randomly shuffle the order of squares

Read More →We could code that strategy in few lines by adding an elif len values test to eliminate. Date September UTC Source Oceans Hypersudoku Solution g The svgdiagram is derivative work from created by Oceanh and uploaded to Wikimedia under Ccby . Now that we have squares units and peers the next step is to define Sudoku playing grid. In fact it turns out that to solve this particular puzzle we need look only possibilities and have explicitly search through of the unfilled squares constraint propagation does rest

Read More →This process called constraint propagation. This why chose to implement the set of possible values for square as string can copy with which simple and efficient. But is this an intrinsicly hard puzzle Or the difficulty artifact of particular variableand valueordering scheme used by my search routine To test randomized changed for values last line be shuffled implemented using

Read More →My program solves them in. Here is the code that defines solve all and uses it to verify puzzles from file as well random import time grids name showif. The alternative is to keep track of each change values and undo when we hit dead end

Read More →Even with these checks my random puzzles are not guaranteed to have one unique solution. So read this assignment statement units dictionary where each square maps to the list of that contain .

This way each branch of the search tree independent and doesn confuse another . My guess is that somewhere early in the search there sequence of squares probably two such if we choose exact wrong combination values to fill it takes about seconds discover contradiction.
