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.
