[6] D. Vanderhaeghe & V. Ostromoukhov: “Polyomino-Based Digital Halftoning” (2008). ↑
For SAT problems with 10 variables and 200 clauses, sometimes outputted UNSAT because it couldn't find any satisfying assignment, and it would take a lot more time to find one, which is logically sound. I don't consider this as bad reasoning as it is about performance. So I tried it with only 100 clauses and it successfully found valid assignments.
