Post automatic solver
I've been seeing this for several weeks. Every day "chip" solves all the puzzles in about 5 seconds. I thought it was something you had put in to check puzzles.

Today his automatic solver failed on the difficult 7x7 though, submitting a solution with only the (given) 5 and 3 filled in,

The problem must be the power in a 4 cell cage. An overflow occurs at bad programming.

I'm thinking the program exits without finding a solution.

The values submiited are actually MAXINT (so probably some initial "impossible" value)
