A lot of information on the subject of threatening hunting and Alan Kahn did not stay aloof. In his post he refreshes in memory several common methods of hunting.
Elan tells about popular methods of hunting:
1. Searching;
2. Clustering;
3. Grouping;
4. Stack Counting.

Sqrrl will simplify most of the complexity and cut out the trivial work.
