Another apporach I think would be modifying the data structure of
hierarchy itself. The idea is to add a counter to ancestors and
descendants.
:ancestors: { :c #{ [:a1 1] [:a2 2] } }
So, the counter 2 on :a2 means how many paths can you get :c to
reach :a2. When the counter reaches 0, you can remove it completely.
Otherwise, decrement it.This approach requires to change all the functions related to hierarchy, and the data structure will be incompatible to the original one. But the speed is gonna be fast. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
