Generalized Greedy Algorithm for Shortest Superstring
نویسندگان
چکیده
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.

A linear time algorithm for Shortest Cyclic Cover of Strings
Merging words according to their overlap yields a superstring. This basic operation allows to infer long strings from a collection of short pieces, as in genome assembly. To capture a maximum of overlaps, the goal is to infer the shortest superstring of a set of input words. The Shortest Cyclic Cover of Strings (SCCS) problem asks, instead of a single linear superstring, for a set of cyclic str...
متن کاملCoevolving solutions to the shortest common superstring problem.
The shortest common superstring (SCS) problem, known to be NP-Complete, seeks the shortest string that contains all strings from a given set. In this paper we compare four approaches for finding solutions to the SCS problem: a standard genetic algorithm, a novel cooperative-coevolutionary algorithm, a benchmark greedy algorithm, and a parallel coevolutionary-greedy approach. We show the coevolu...
متن کاملOn the Greedy Superstring Conjecture
We investigate the greedy algorithm for the shortest common superstring problem. We show that the length of the greedy superstring is upper-bounded by the sum of the lengths of an optimal superstring and an optimal cycle cover, provided the greedy algorithm happens to merge the strings in a particular way. Thus, when restricting inputs correspondingly, we verify the well known greedy conjecture...
متن کاملSequential and Parallel Algorithms for the Shortest Common Superstring Problem
We design sequential and parallel genetic algorithms, simulated annealing algorithms and improved greedy algorithms for the shortest common superstring problem(SCS), which is to find the shortest string that contains all strings from a given set of strings. The SCS problem is NP-complete [7]. It is even MAX SNP hard [2] i.e. no polynomial-time algorithm exists, that can approximate the optimum ...
متن کاملShortest Superstring
In the Shortest Superstring problem (SS) one has to find a shortest string s containing given strings s1, . . . , sn as substrings. The problem is NP-hard, so a natural question is that of its approximability. One natural approach to approximately solving SS is the following GREEDY heuristic: repeatedly merge two strings with the largest overlap until only a single string is left. This heuristi...
