I am looking for ANSI C HAT-trie implementation released under some free license. I have not found one. Can you point me to some standalone implementation or a program that uses HAT-tries to get at least slight idea how to implement it the roght way, please?
The original paper on HAT-trie can be found here: http://crpit.com/confpapers/CRPITV62Askitis.pdf
PS: In case faster cache-conscious data structured well-suited for strings evolved since the time the above paper was written, please point me to the papers or example source codes rather.
