The power of this approach will become apparent when we show the ease with which it extends to solving several generalizations of the set cover problem (see Section 13.2).

Steiner Tree and TSP case. For TSP, without this restriction, the problem admits no approximation factor, assuming . ≠ .. The algorithms, and their analyses, are similar in spirit, which is the reason for presenting these problems together.
