I'm familiar with the path compression technique for union-find, but I tend not to use it for two reasons:
1. That technique generally assumes you are going to continue to compress the path with each *find* operation, not just the union. This means you need to either use a mutable structure or else the find operation needs to also return a new structure with compressed paths each time you do a find, and you need to thread that through to the next find, which is awkward. 2. I find that most of the time, after building the structure, I want to list out all the components or count the components or otherwise do something to each component. With the path compression version, you can't answer any of those basic questions without fully flattening it. If you like the path compression approach, here's another Clojure implementation: https://github.com/jordanlewis/data.union-find -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
