+
+-- This is a bit complex, as the purpose is to find male flowers at horizontal distances of over
+-- 100 nodes. As searching such a large area is time consuming, this is optimized in four ways:
+-- - The search result (the locations of male trees) is cached, so that it can be used again
+-- - Only 1/9th of the desired area is searched at a time. A new search is only performed if no male
+--   flowers are found in the previously searched parts.
+-- - Search results are shared with other female palms nearby.
+-- - If previous searches for male palms have consumed too much CPU time, the search is skipped
+--   (This means no male palms will be found, and the pollination of the flowers affected will be
+--   delayed. If this happens repeatedly, eventually, the female flowers will wither...)
+-- A caching method was selected that is suited for the case where most date trees are long-lived,
+-- and where the number of trees nearby is limited:
+-- - Locations of male palms are stored as metadata for every female palm. This means that a player
+--   visiting a remote area with some date palms will not cause extensive searches for male palms as
+--   long overdue blossoming ABMs are triggered for every date palm.
+-- - Even when male palms *are* cut down, a cache refill will only be performed if the cached results do not
+--   contain a male palm with blossoms.
+-- The method will probably perform suboptimally:
+-- - If female palms are frequently chopped down and replanted.
+--   Freshly grown palms will need to search for male palms again
+--   (this is mitigated by the long blossoming interval, which increases the chance that search
+--    results have already been shared)
+-- - If an area contains a large number of male and female palms.
+--   In this area, every female palm will have an almost identical list of male palm locations
+--   as metadata.
+-- - If all male palms within range of a number of female palms have been chopped down (with possibly
+--   new ones planted). Although an attempt was made to share search results in this case as well,
+--   a number of similar searches will unavoidably be performed by the different female palms.
+-- - If no male palms are in range of a female palm. In that case, there will be frequent searches
+--   for newly-grown male palms.
+
+-- Search statistics - used to limit the search load.
