Abstract

In the primitive greedy algorithm for shortest superstring, if a pair of strings with maximum overlap picked out, they are subsequently merged. In this paper, we introduce the concept of optimal set and generalize the primitive greedy algorithm. The generalized algorithm can be reduced to the primitive greedy algorithm if the relative optimal set is empty. Consequently, the new algorithm achieves a better bound at the expense of cost. But the cost is acceptable in practice.

Keywords: greedy algorithm shortest superstring optimal set
