Linear-time approximation algorithms for minimum subset sum and subset sum

Liliana Grigoriu (liliana.grigoriu***at***gmail.com)

Abstract: We present a linear-time approximation algorithm for minimum subset sum, which has better worst-case approximation factor (6/5) than previous linear-time algorithms for this problem.We also present a generalization of the scheme used to derive the algorithm, which can be used to obtain algorithms with approximation ratios of k+1/k. In addition, we present a family of linear-time approximation algorithms for subset sum with worst-case approximation factors of k/k+1 assuming that k is constant.

Keywords: subset sum; minimum subset sum; linear-time approximation; approximation algorithms
