Constraint Satisfaction Problems Parameterized Above or Below Tight Bounds: A Survey

  author={Gregory Gutin and Anders Yeo},

We consider constraint satisfaction problems parameteriz ed above or below tight bounds. One example is MaxSat parameterized abo ve m/2: given a CNF formulaF with m clauses, decide whether there is a truth assignment that satisfies at least m/2 + k clauses, wherek is the parameter. Among other problems we deal with are MaxLin2-AA (given a system of linea r quations over F2 in which each equation has a positive integral weight, decid e whether there is an assignment to the variables that… CONTINUE READING
