I finally decided to write my own puzzle solver/generator. Here's a sample "easy" puzzle. I'll post more later, when I get more sophisticated solving algorithms running. My hope is to recognize and develop new solving strategies or patterns, in order to fill in the gap between foilman's "hard" and "very hard" levels, if such a thing can be done.

Here's a sample "medium" puzzle, although I think it's probably at least a Thursday puzzle. (I also have planned "hard" and "insane" difficulty levels, so don't say I'm not ambitious.) Let me know what you think.

Is your solver pattern based with some additional simple logic, or no-patterns + complex logic?

Here are the puzzles in loopy format. Just go to Game -> Specific and paste the string. There's a bug in the newest versions, but I have r6879 and it works fine. (Jankonyex gave a link to r6724 in another thread.)

I've gone through three different setups, but (to make the story short) what I have now is just simple logic + no patterns. I'll be implementing some complex stuff soon, hopefully.

I'll see how my solver rates them when I get home then.(My solver doesn't use any patterns, but it does support some more complex logics)

Is this second one ambiguous, or do I need coffee? BTW, what I've shown isn't forced, if I'm right there are even more solutions, but this partial solution shows it best:

You're right. I copied it down wrong! There should be a 1 in row 5, column 9 (above the two 2's). So sorry... Of course now I have it all automated.

Here are a couple more "medium" puzzles. I copied-pasted (a fool-proof method) so there shouldn't be any mistakes with these.

Nice, good idea - I'm looking forward to giving these a go when I get a bit more time! Can your generator create symmetrical puzzles? To me if a puzzle doesn't have some kind of symmetry in it, it doesn't look "right"...

Good point. It can, although it would be take longer to generate a "minimal-clue" puzzle.

I think I'm cutting out one difficulty level. Will update more later...

Yes, I thought it was nice. And that was the first puzzle it ever generated! Since it doesn't use pattern recognition (right now), that pattern was sort of spontaneous and novel, which is what I was hoping for.

Here are a couple more, this time rated "hard". Sorry for the lack of symmetry... I'll add that soon.

symmetrical puzzle is really necessary,
otherwise some puzzles would become "too" difficult.

Very cool .

I changed some things, so those two puzzles have been demoted to "medium" difficulty. Here is another "medium" puzzle, although I think it's hard. I spotted some new (or rare) patterns. Have fun.

Aha! Your loopy screenshot has finally let me understand some of the things you've been saying, Jankonyex. Virtual 2s, and using the e's and o's on three corners of a square to determine whether the last corner is an entry point to an isolated region. Brilliant, both of them. Do you actually get to use them very often?

My contribution is not nearly as cool as that, I'm afraid. I've managed to use it only once: it turns up often enough, but there are usually easier ways to solve the puzzle.

Well, if you've felt a little uncomfortable doing these puzzles, I have some good news: symmetry!

10x7:a013221a2f2b1a22b3a3212a1b22b1a3131a2b22a1b1f3a232222a


10x7:b12a22a1a2b1a21a2a20a02b211b1d2b122b13a33a1a12a1b1a2a22a22b


My fear was that adding symmetry would really cut down on the difficulty (at least in how my program generates puzzles), but I think these are fairly challenging. I'm still seeing new patterns and strategies here--do others feel the same way? Or am I lost in my own little world...
