The Shortest Common Superstring (SCS) problem is a classical combinatorial problem on strings with applications in many domains, e.g. DNA fragment assembly, data compression, etc. (see [6] for a recent survey). It consists, given a finite set of strings S over an alphabet Σ, in finding a shortest string ...

Web2. Application of a greedy heuristic to the shortest common superstring problem (SCS): Given a set of strings, find the shortest string such that every input string is a substring of the generated string. This problem has applications in data compression and in DNA sequencing. Since SCS is NP-hard, fast heuristics are important. Requirements: 1.
