For each found puzzle, the following information is shown:
Example: medium puzzle 885 by Rodolfo Kurchan
Should be self explanatory. The beginning of the line is a link that will take you to the pips-analyzer.app solutions tab and display that unsolved puzzle.
Example: Board: 6x4, Valid Cells: 14, Invalid Cells: 10
The board size (WxH) gives the dimensions of the smallest bounding rectangle that contains all the valid board cells. The Valid/Invalid Cells are counts of the valid and invalid cells within that rectangle. Note that for a puzzle to be valid, the number of Valid Cells must be 2 times the number of dominoes.
Example: Constraints: 8, Constrained Cells: 11, Unconstrained Cells: 3, Fixed Constraints Sum: 8
Example: Dominoes: 7, Total Pips: 49, Blank: 2, Ones: 0, Twos: 1, Threes: 4, Fours: 2, Fives: 3*, Sixes: 2*
Example: Domino Weights: 4-3: 7, 3-2: 5, 4-0: 4, 0-3: 3, 5-5: 10, 5-3: 8, 6-6: 12
Lists every domino and its weight, which is defined as the sum of the pips on its two ends.
Example: Domino Weight Counts: 3: 1, 4: 1, 5: 1, 7: 1, 8: 1, 10: 1, 12: 1
For each domino weight (from the list above), counts how many times that weight occurs. Useful in answering questions like "is there a single domino totalling 8" ("yes" in this example).
Example: Solutions: 4 (all) [solve time 0.457]
Gives the number of solutions, including all trivial swaps and rotations. The value in parenthesis will almost always be "all", except in exceedingly rare cases where the Pips-Analyzer solver is unable to find all solutions in a reasonable time, in which case this will show the solution count limit. The solve time, in brackets, gives the time (in seconds) to find the solutions.
Below the solutions summary is one line for each solution.
Example:
Solution 1*: 4-3@f2:f3, 3-2@c1:d1, 4-0@f1:e1, 0-3@e2:e3, 5-5@a2:b2, 5-3@f4:e4, 6-6@a1:b1 Solution 2: 4-3@f2:f3, 3-2@c1:d1, 4-0@f1:e1, 0-3@e2:e3, 5-5@a1:b1, 5-3@f4:e4, 6-6@a2:b2 Solution 3: 4-3@f2:f3, 3-2@d1:c1, 4-0@f1:e1, 0-3@e2:e3, 5-5@a2:b2, 5-3@f4:e4, 6-6@a1:b1 Solution 4: 4-3@f2:f3, 3-2@d1:c1, 4-0@f1:e1, 0-3@e2:e3, 5-5@a1:b1, 5-3@f4:e4, 6-6@a2:b2
The beginning of each line is a link that will take you to the pips-analyzer.app solutions tab and display that puzzle solution (and the neighboring solution if there is one). The solution marked with a * is the one provided by the puzzle author.
Each solution is a list of domino@location pairs. Each location is the position of the two ends of that domino on the board (end1:end2). The positions use chess notation - a letter specifies the file (column) and a number specifies the rank (row). Note that position a1 is always the lower-left corner of the bounding rectangle, which may or may not be a valid cell in the board.
If there are multiple solutions, then after they have all been listed, there will be a Placements line which gives the number of different locations each domino appears in across all solutions. In addition, in the solutions list, highlighting will indicate which dominoes are in different locations as compared to the previous solution (i.e., what moved). Finally, there will be a Cell/Values table listing every valid cell on the board, along with every value that appears in that cell, across all solutions.
