     4. (Computers) Based on the use of an efficient trial-and
        error method to search a space of possible solutions to a
        problem, or to find an acceptable approximate solution,
        when an exact algorithmic method is unavailable or too
        time-consuming.

From The Free On-line Dictionary of Computing (27 SEP 03) [foldoc]:

  heuristic
       
          1.  A rule of thumb, simplification, or educated
          guess that reduces or limits the search for solutions in
          domains that are difficult and poorly understood.  Unlike
          {algorithms}, heuristics do not guarantee optimal, or even
          {feasible}, solutions and are often used with no theoretical
          guarantee.
       
          2.  {approximation algorithm}.
