If you have an NP problem of the 'optimizing' sort (such as TSP),
there are various search algorithms that can find solutions that
are very close to the optimum in a reasonable amount of time.

Also, NP problems are by their very nature eligible for large-scale
distributed computing, even across multiple networks.

The same is not necessarily true for all O(exp) problems.
