Polarised random κ-SAT
In this paper we study a variation of the random κ-SAT problem, called polarised random κ-SAT, which contains both the classical random κ-SAT model and the random version of monotone κ-SAT another well-known NP-complete version of SAT. In this model there is a polarisation parameter p, and in half of the clauses each variable occurs negated with probability p and pure otherwise, while in the other
