The Longest Haplotype Reconstruction (LHR) problem has been introduced in Computational Biology for the reconstruction of the haplotypes of an individual, starting from a matrix of incomplete haplotype fragments. In this paper, we reconsider the LHR problem, proving that it is NP-hard even in the restricted case when the input matrix is error-free. Then, we investigate the approximation complexity of the problem, showing that it cannot be approximated within factor 2logδ nm for any constant δ poly log nm]. Finally, we give a fixed-parameter algorithm, where the parameter is the size of the reconstructed haplotypes. |
