Sequencing by Hybridization with Positive Faults

The paper is concerned with a computational phase of the sequencing DNA chains by hybridization. It is assumed that positive faults can occur in the hybridization experiment. An approach based on a reduction of the problem to a variant of a Selective Traveling Salesman Problem and an algorithm for solving the latter, have been proposed. The algorithm behaves extremely well, even for a fault rate exceeding 50%.
