MLPACK is a C++ machine learning library with emphasis on scalability, speed, and ease-of-use. Its aim is to make machine learning possible for novice users by means of a simple, consistent API, while simultaneously exploiting C++ language features to provide maximum performance and flexibility for expert users. * More info + downloads: https://mlpack.org * Git repo: https://github.com/mlpack/mlpack

Java generic API for search algorithms on graphs implicitly given by tree node expansion operator

B-tree with a twist pointer set. The ordered set approaches the speed of the fastest unordered, hash table based sets, while using several times less memory.

...And as already mentioned, it's just the most efficient tree-based sorting algorithm that you can get. But furthermore this way of finding primes interestingly leaves a hard nut to crack for mathematicians: In very rare cases it finds numbers that are not primes. For all primes below one million this phenomenon arises in exactly two cases: 31213 which is 7 * 7 * 7 * 7 * 13 336141 which is 3 * 3 * 13 * 13 * 13 * 17 Who can explain, why?

Efficiently create compact, highly customizable tree layouts - Based on Walker's algorithm with enhancements suggested by Buchheim, Jünger, and Leipert the software builds tree layouts in linear time. I.e. even trees with many nodes are built fast. Downloads are available at https://sourceforge.net/projects/treelayout/files/. For detailed documentation look at the TreeLayout web site http://treelayout.sourceforge.net/.

The library for utilization of Minimal Quadtree format for storing very large sparse matrices. Please see the paper referenced below for the description of a problem.

S-Match is a semantic matching framework. S-Match takes any two tree like structures (such as database schemas, classifications, lightweight ontologies) and returns a set of correspondences between those tree nodes which semantically correspond to one another. S-Match contains implementations of the semantic matching, minimal semantic matching and structure preserving semantic matching algorithms.

CLAW is a C++ Library providing various tools in different domains, like a Tweener framework, Bézier curves manipulation, a map with multiple value types, a binary search tree container implemented as an AVL and an implementation of the sockets as std::stream. The library also includes a set of classes to easily load and write png, jpeg, gif files and other image formats. Finally, a part of the library is devoted to artificial intelligence in games and includes a generic alpha-beta algorithm. Each module is provided with an example program.

...It is an approximation of k-means that is practically constant in data size and applies to arbitrarily high dimensions but can only scale to a few thousands of centroids. As a by-product of training, a tree structure performs either exact or approximate quantization on trained centroids, the latter being not very precise but extremely fast. A detailed README file describes the usage of the software, including license, requirements, installation, file formats, sample data, tools, and options. With the sample data provided and the default options, it is possible to test the code immediately as a demo. ...

the c prototyping tools library provides thread-safe linked list, priority queue, hash table, hash list, AVL tree and trie implementations, as well as a thread pool and thread management framework, a tcp and http socket api, and a dbms abstraction layer.

An interactive binary search tree. The user may interact with the tree by performing rotations, balancing, insertions, and deletions. For educational purposes

Fast cython implementation of trie data structure for Python. Development is inactive, but moved to: http://github.com/martinkozak/cytrie.

The gsuffix library implements serveral algorithms used for enumerative string searches. It incorporates the suffix tree and suffix array data structures as well as some other methods.

This small C package is made of an independent AVL tree library, and of an extension module for Python that builds upon it to provide objects of type 'avl_tree' in Python, which can behave as sorted containers or sequential lists.

Alternative approach to minimum redundancy coding (fixed-length) without using tree data structures. The main advantages are simplicity and flexibility.

This is a fully STL-compliant C++ map/set/multimap/multiset implementation for g++ using an AVL tree instead of a Red-Black tree (that is present in current libstdc++).

This is an avl tree implementation. It is implemented in very optimized way and easy to use. It does not force you to use any specific way of memory allocation. It does not use recursive call. It is implemented with emphasis on speed and simplicity.

Classic game solved with MinMax algorithm (full solution tree) and simple Heuristics. Specially for learning and teaching computer AI

spdict is a library of dictionary algorithms written in C++. It has support for sorted array, binary search tree, red-black tree, skip list, and balanced tree algorithms. Also include a cache class.

JSONER is a JavaScript library intented to simplify most used operations with JSON based on event API on JSON tree. It includes: data lookup and binding solution, HTML form by JSON dynamically creation and population, transformation and comparison JSONs.

A Java API for using suffix trees with natural language and an Eclipse/SWT-based GUI for suffix tree visualization using Graphviz.

A library of data structures with a unified API, written in portable C. Lists (uni- and bidirectional), a vector, a hash, a balanced tree (RB or AVL), a heap and tuples. Memory management, clone support, error handling.

The tree control library is a C++ container library which stores generic types in tree structures. Three containers are available in the library: tree, multitree, and unique_tree. The library usage and syntax is much like that of the STL.

The treexpr library is a Free Software library that applies regular expression concepts to tree structures. It it written in C and has a JNI binding to Java.
