Advanced methods and approaches for solving Sudoku puzzles

### What is the notation used here?

I see stuff like
Code: Select all
`6[78][134789][178][578][58][13479][347]2 `

I would expect to see stuff like
Code: Select all
`--- 13- --5-4- --- 2--8-- 9-- ------ -5- 9----2 --- 4----3 -6- ------ -13 --6--5 --- -1-71- -28 ---`

etc. to describe a puzzle.

And for pencilmarks, just
Code: Select all
`269       2679      679       24678     478       2467      678       4789      4789     35        35679     1679      678       78        567       13678     379       1379     12356     35        167       24567     47        24567     1367      347       1347     146       678       4678      23478     478       147       13678     23678     12378    1569      56789     16789     378       789       179       135678    35678     1378     1459      5789      14789     2478      4789      1479      1578      2578      1278     249       289       489       457       479       4579      578       245789    24789    2346      2368      4689      467       479       4679      378       234789    23478    3469      369       469       456       49        4569      35        3459      349      `

Where is the notation used here described. It it standard everywhere, or just here?

The notation you describe would be nice, but it's a bit niggly to format, and very wide, so each row goes on to two lines if your window's not wide enough.

I have looked at the notations for these puzzles and am also not understanding it. But I assume since there are 9 rows and 9 columns, that each line of text is describing the possible numbers in each of the boxes. I am also assuming the data is formatted left to right and top to bottom. I take a 9 x 9 set of cells in an Excel spreadsheet and fill in the cells with the data. I only get confused when a comma or {} is missing. I assume a single digit by itself is solved cell that was GIVEN.

Even if I get it wrong I still end up with interesting puzzles that are fun to solve. If there are rules on the formatting I have not found them yet.

I'll keep watching and reading til then.

Each line usually represents an individual row, not box, starting with the top row. Not confusing really, just hard to visualize, since the columns don't line up on the screen.
