The New Sudoku Players' Forum

[denis_berthier]

.
François has extended the SHC so as to allow sukakus as inputs any time sudokus were allowed. In both cases, the standard 81- or 729- character format is used.
Moreover, a sukaku grid can be copied into a file from almost any grid on the forum, with (almost) any "markings" of the candidates (except a single quote or a paragraph sign, for technical reasons apparently related to java portability).
Allowed markers on candidates: upper and lower cases letters (with no accent) plus the following signs: #&@$(=+-*^%)_,;/
Allowed separators between cells on a line: space | ! : (at least one separator between two cells is mandatory).
See the README.md file for details.

In the README.md file, I've rewritten the command line syntax in such a way that:
- any consistent command that worked before still works (example of an inconsistent command: java -jar SHC.jar B -examples -puzzle);
- one doesn't have to specify the game is sudoku, only the sukaku keyword must be added after the <classif>.

Let us know if this is a useful addition for you.

Doesn't SHC start searching from the shortest Braid at every step? Is this intentional or a bug?

[denis_berthier]

.
I don't see any problem. SHC computes the B rating, 28. Does your solver find anything different?

SudoRules applies the simplest-first strategy at each step. SHC doesn't have such constraints.

Hi Mike
Thanks for the reference.

There was a time when puzzles in T&E(1) with such a high B rating were a rarity. I've recently defined a procedure to produce many in a systematic way from T&E(3) or T&E(2) ones: http://forum.enjoysudoku.com/1-brt-expansion-paths-within-t-e-n-and-beyond-t45647-98.html

It often happens for such extreme cases that a single braid downgrades the puzzle to a much lower B rating - as appears here.
