WebMar 1, 2016 · Greedy algorithm. 1. Introduction. 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 ...
