It turns out this isn't a bug. Removing the center clue results in a puzzle with multiple solutions. I didn't realize it because the Analyzer results looked the same as for valid puzzles, due to an apparent bug in the Analyzer which causes it to terminate prematurely on some valid puzzles. I think t...

In looking at the other Analyzer problem again, I think I got it backwards. I think that the Analyzer produces the correct results when the puzzle is first opened, and incorrect results if you click Restart, and then Analyze again. I think that the first puzzle's score should be 2539, not 1124.

I think I might understand what's happening. In this case, when the Optimizer removes the center clue, the Analyzer score indicates that the resulting puzzle is easier than the original. I don't think that it should work that way. When you remove a clue from a puzzle, the puzzle always gets harder. ...

I entered the following puzzle in SudoCue, and clicked on Optimize - Keep Symmetry. It didn't find a more minimal puzzle. However, if you remove the 5 from the center square, the puzzle is still valid and symmetrical. . . .|1 3 9|. . . . . 6|. . .|. . . . . 4|. . .|8 3 . -----+-----+----- 2 . .|4 . ...

Thanks for the explanation of why the non-minimal puzzle had a higher score than the minimal puzzle. My own puzzle maker's rating algorithm doesn't do a very good job at all. Rating puzzles seems to be a harder problem than creating them. The other Analyzer problem occurs when I open a puzzle and in...

I've just downloaded SudoCue and have been experimenting with the Analyzer and Optimizer on my own puzzles. I used Optimize with Keep Symmetry on this puzzle: ...9...2. ..7.8.3.. .9...6..8 3..8...5. ..4.9.7.. .6...2..1 4..7...8. ..1.4.2.. .5...1... and it gave me this puzzle: ...9...2. ..7.8.3.. .9....
