of those, store the state and guess. It uses a stack like system for the states. It was/is solving puzzles in about 2.75 ms. I think it will solve any puzzle that can be solved, and with a little modification, will check if more than one solution exists.Where's the code? -SC

From a brief look it doesn't seem that it handles several more advanced analytical techniques. For example if all the posibilities for a number within a box reside on the same row or column, then it is required that the other boxes that contain that column not have it within the column. Etc, There are some really advanced ones like X-Wing etc. I don't fully understand those techniques yet though. I'll post my current code here monday or so.

The workaround is to make the ctor for the inner class take a reference to its owning outer class, then you can use the syntax Inner dup() { Inner n = outerThis.new Inner(outerThis); return n; } That is, you can 'new' the inner class using the outerThis reference. I suppose another way would be to do some terribly ugly, nonportable hacks to _find_ the outer pointer manually. Maybe if we do that, Walter will see that having an 'outer' reference would be useful.
