Web17. This list will be very long;) Here are some of my favourite (NP-complete) variants of SAT: PLANAR ( ≤ 3, 3 )-SAT (each clause contains at least two and at most three literals, each variable appears in exactly three clauses; twice in its non-negated form, and once in its negated form, and the bipartite incidence graph is planar.) WebSat and Max Sat are among the most prominent problems for which local search algorithms have been successfully applied. A fundamental task for such an algorithm is to increase the number of clauses satisfied by a given truth assignment by flipping the truth values of at most k variables (k-flip local search).For a total number of n variables the size of the …
