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.

TSPSG is intended to generate and solve "travelling salesman problem" (TSP) tasks. It uses the Branch and Bound method for solving. Its input is a number of cities and a matrix of city-to-city travel costs. The matrix can be populated with random values in a given range (which is useful for generating tasks). The result is an optimal route, its price, step-by-step matrices of solving, and a solving graph. The task can be saved in an internal binary format and opened later. The result can be printed or saved as PDF, HTML, or ODF. TSPSG may be useful for teachers to generate test tasks or just for regular users to solve TSPs. Also, it may be used as an example of using the Branch and Bound method to solve a particular task.

php mudnames is a PHP class that can generate random names for characters used in role playing games such as multi-user dungeon (MUD) games. Although the names do not mean anything, they sound very much like typical names of characters that you often see in this kind of game. It can retrieve text data from one of several dictionary files. The dictionary data is used to generate random names based on selected capabilities and used particles.

markov.sql implements third order (and lower) model Markov Chains, including training and generation, in pure SQL(ite). The source code archive also contains a pre-trained SQL dump with models based on the 1990 US Census Bureau data sets for first and last names, and an excerpt of the 2012 US tax office corporation names.

AlgART Libraries is a collection of Java libraries, supporting generalized smart arrays and matrices with elements of any types, including a wide set of of 2D, 3D, and multidimensional image processing and other algorithms. Main features: 64-bit long int indexes, a memory model concept (allowing storing data in different schemes from RAM to mapped disk files), wide usage of lazy evaluations, built-in multi-threading optimization for multi-core processors, etc.

Algorithm Study provides tools and resources to augment the traditional study of algorithms. It includes implementations of common and less-common algorithms in a variety of languages and visualization tools to help in gaining a deeper understanding of the algorithms. The algorithm implementations are each accompanied by a discussion of the asymptotic ("big O") run time and memory limits of the algorithm. Some implementations include discussion of how the algorithm or data structure is commonly used and comparisons with similar algorithms or data structures. All implementations have test cases that exercise their functionality. The visualization tool, Algorithm Visualizer, displays what happens as various algorithms do their work.

Zebra_MPTT is a PHP class that provides an implementation of the modified preorder tree traversal algorithm. It provides methods for adding nodes anywhere in the tree, deleting nodes, moving and copying nodes around the tree, and for retrieving information about the nodes. It uses table locks to ensure that database integrity is always preserved and that concurrent MySQL sessions don’t compromise data integrity. A caching mechanism ensures that regardless of the type or the number of retrieval operations, the database is read only once per script execution.

BS is a data structures library. It features fixed size, random access sequences. The sequences are constructed over B-trees. Complexity for most single item operations is about O(logN). The sequences are three to five times faster over random access BST-based sequences, while having better memory usage characteristics.
