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.
SupplyChain is a C++ library that simulates a supply chain. It takes full advantage of concurrent programming and multi-core CPUs without the programmer having to know anything about it. A supply chain consists of two mandatory components: initial producers and final consumers. Apart from these components, a supply chain can include any number of manufacturer nodes. Each node can contain any number of elements of its own type. These elements allow very powerful supply chains to be modeled and constructed.
EpochX is a genetic programming framework. It is designed specifically for the task of analyzing evolutionary automatic programming, so is ideal for researchers who require an extendable system for studying the effects of new operators or procedures. It supports 3 popular representations - Strongly-Typed tree GP, Context-Free Grammar GP, and Grammatical Evolution.
EO is a template-based, ANSI-C++ evolutionary computation library that helps you to write your own stochastic optimization algorithms quickly. Evolutionary algorithms form a family of algorithms inspired by the theory of evolution, and solve various problems. They evolve a set of solutions to a given problem in order to produce the best results. These are stochastic algorithms because they iteratively use random processes. The vast majority of these methods are used to solve optimization problems, and may be also called "metaheuristics". They are also ranked among computational intelligence methods, a domain close to artificial intelligence. With the help of EO, you can easily design evolutionary algorithms that will find solutions to virtually all kind of hard optimization problems, from continuous to combinatorial ones.
LibAPCNIS is a PHP library for accessing the NIS port of the Apcupsd UPS Monitoring daemon. It allows you to access realtime UPS stats from a PHP script without having Apcupsd installed. It does not require the apcaccess application included with an Apcupsd installation, and there are no external dependencies.
