Projects / nedtries


nedtries is a portable in-place bitwise binary Fredkin trie algorithm that allows for near constant time insertions, deletions, finds, closest fit finds, and iteration. It is approximately 50-100% faster than red-black trees and up to 20% faster than O(1) hash tables. It provides implementations as C macros, C++ templates, and as a C++ STL compatible associative container.

    Release Notes: This release fixes three major bugs since 1.01 RC1: the STL iterators were improperly implemented, there was memory corruption on 64 bit C++ STL container emulation usage, and "nearest find" did a close find, not a nearest find.
