It is known that large fragments of the class of dense
Minimum Constraint Satisfaction (MIN-CSP) problems do not have
polynomial time approximation schemes (PTASs) contrary to their
Maximum Constraint Satisfaction analogs. In this paper we prove,
somewhat surprisingly, that the minimum satisfaction of dense
instances of kSAT-formulas, and linear equations mod 2, Ek-LIN2,
do have PTASs for any k. The MIN-Ek-LIN2 problems are equivalent
to the k-ary versions of the Nearest Codeword problem, the problem
which is known to be exceedingly hard to approximate on general
instances. The method of solution of the above problems depends on
the developement of a new density sampling technique for k-uniform
hypergraphs which could be of independent interest.
