Shortest Common Superstring<br />

Notes: <strong>The</strong> shortest common superstring problem and its application to DNA shotgun assembly is ably<br />

surveyed in [Wat95]. Kececioglu and Myers [KM95] report on an algorithm for the more general version<br />

of shortest common superstring, where the strings may have errors. <strong>The</strong>ir paper is recommended reading<br />

to anyone interested in fragment assembly.<br />

Blum et al. [BJL 91] gave the first constant-factor approximation algorithms for shortest common<br />

superstring, with a variation of the greedy heuristic. More recent research has beaten the constant down<br />

to 2.75, progress towards the expected factor-two result.<br />
