WebWhen it fails, the problem is NP-hard and, in fact, APX-complete (hence, cannot be approximated better than some constant). Thus, we establish a dichotomy in the complexity of computing an optimal S-repair. We present general analysis techniques for the complexity of computing an optimal U-repair, some based on the dichotomy for S-repairs. Webthis case, our dichotomy for S-repairs provides the precise test of tractability. We also show decomposition techniques that extend the opportunities of using the dichotomy.
