摘要: Pairwise end sequencing is a very useful method for whole genome which determines the complete DNA sequence of an organism's with help laboratory processes. Pairedend interval cover problem derived from pairwise sequencing. A paired-end S constituted at most two disjoint intervals, and can be described as given family F find least number pairedend intervals to S. We prove that NP-complete. The c-interval generalization allows each member have c intervals. It extends classical set-cover reasonably. show APX-hard when ≤ 3. For solving these problems, we present polynomial-time 6c-approximation algorithm fixed parameter tractable k-bounded problem. Our implementation results approximation ratio much smaller than theoretical bound real examples.
