While a few days ago I found one which resulted in a high number of 8 clues puzzles, today's one results only in very easy puzzles. I think it's layout dependent. This one is to symmetrical from design. Even when I generate with the forcing net option on the highest rated puzzles I can get are:
- Code: Select all

....9.....1.....9....964......3.7...............8.6......135....5.....4.....5....

Me too. It stops with Naked/Hidden Subsets and Pointing/Claiming.
When generating from a fully solved puzzle as input, randomly some (symmetrical) cells will be emptied and then SiSeSuSo tries to solve it with the checked methods.
A next try will randomly empty different cells, and mayby you are lucky.
If you try not symmetrical (In Gen_Params) some progress is made (your first puzzle/solution):
- Code: Select all
#1/WX/B4,JS
...49......2......3............178............9..4.3..........6......2...........

Response to the rest in blue:Is it through the number of solving methods in SiSeSuSo that need to be augmented with some essential ones like AIC's?
Also X-Chain, XY-Chains and Fish are rare. AIC is on top of my TODO-list, together with "grouped" methods, but I find it hard to program.The generator needs forcing nets so that the solver can use turbot-fishes as solving method.
Without those nets all generated puzzles will result in maximum pointing/claiming and very rarely in additional generalized intersection moves.
No, but if you check all methods, it is not necessary that the resulting puzzle needs all checked methods I'm interested if generating with JigsawExplainer will confirm this maximal rating for this layout.
You will have to generate a lot of puzzles to find a few harder ones.
Sad but trueOther generators can create a lot faster a puzzle (from a fully filled grid or from a complete empty grid), but checking if the puzzle is valid is done by BruteForce/Backtrack. If there are 2 or more solutions, this is an invalid puzzle. So you can generate 100's of puzzles pretty quick (task A).
But at the end all those puzzles need to be solved with logical methods (task B) before it can be decided which methods must be used and/or what the SE Rating is.
In SiSeSuSo task A and B are combined and manually.
