Re: Jigsaw Samurai

Postby urhegyi » Fri Jan 22, 2021 3:09 pm

How would I write a samurai definition in JigsawExplainer with a mixture of types?
How can I mark the grids that have the x-property. So in my last example I have 2 jigsaws , one normal grid and 2 grids with diagonals. Do I have to let any line be followed by an encoding of the type?
Can I write something like:
Code: Select all
.72...9...8....3.2........8......1.626..14......3.......91.....7...6.......7..... 111222333111222333111222333444555666444555666444555666777888999777888999777888999 JSX

The jigsaw definition for the 3rd (middle) grid is incorrect - it looks like a repeat of g2.
JigsawExplainer + samurai has some code support for X, its never been tested, and it has some known bugs.
The 'JS' is optional (not needed, as its default), X is currently treated as Jigsaw! and JSB is not supported (no code!).
So above jigsaw samurai cannot be fully solved/rated.

Corrected the copy and paste error.
When I use the -h -c parameters all grids are treated as jigsaw and when I use the -h -c -X parameters all grids are treated as JSX.
So I see no way to make g1 and g5 JSX and g3 a JS.

As I mentioned earlier the current JigsawExplainer samurai solver treats all grids as jigsaws (JS) so will not solve this.
If you just wanting a rating for your jigsaw samurai:
Code: Select all
.72...9...8....3.2........8......1.626..14......3.......91.....7...6.......7..... ED=2.9/1.2/1.2
