Abstract

Generalised CNFs are considered using such literals, which exclude exactly one possible value from the domain of the variable. First we consider poly-time SAT decision (and fixed-parameter tractability) exploiting matching theory. Then we consider
irredundant generalised CNFs, and characterise some extremal minimally
unsatisfiable CNFs.
