What the no free lunch theorems really mean how do you improve search algorithms?

The result is the no free lunch theorem for search (NFL). It tells us that if any search algorithm performs particularly well on one set of objective functions, it must per- form correspondingly poorly on all other objective functions. This implication is the primary significance of the NFL theorem for search.
