摘要
We prove optimal, up to an arbitrary epsilon > 0, inapproximability results for Max-Ek-Sat for k greater than or equal to 3, maximizing the number of satisfied linear equations in an over-determined system of linear equations modulo a prime p and Set Splitting. As a consequence of these results we get improved lower bounds for the efficient approximability of many optimization problems studied previously. In particular, for Max-E2-Sat, Max-Cut, Max-di-Cut, and Vertex cover.
