Abstract

The approach described in this paper, the shifting strategy, has proved useful in a large variety of contexts. Via the use of this approach we were able to derive algorithms that are the best possible in the sense that the exponential dependence on 1/ɛ cannot be removed unless NP=P. We also note that all other polynomial approximation schemes that we are familiar with rely on dynamic programming. The technique we introduced is an alternative to dynamic programming for the construction of polynomial approximation schemes for strongly NP-complete problems.
