Computational Aspects of DNA Sequencing by Hybridization – a Survey

Sequencing by hybridization (SBH) is a method of reading DNA sequence from its smaller fragments. Such a method has been proposed in late 1980s and until the emergence of the new generation sequencing it has been widely used and improved. Since the initial, classical approach to SBH, many modifications and enhancements was proposed, aimed at improving the preciseness and the length of sequences which can be unambiguously read. Even now, for some DNA sequences sequencing by hybridization can still be used effectively and at a low cost. In this paper many different approaches to the SBH will be described, mainly from the points of view of algorithms and computational complexity.
