AAFID (Autonomous Agents for Intrusion Detection) is a distributed monitoring architecture with an orientation towards Intrusion Detection developed at the CERIAS at Purdue University. AAFID2 is a prototype implementation of the architecture that includes several ready-to-work agents, plus development facilities for writing your own.
ABC Path Generator is a program and a Perl library that generates layouts of ABC Path based on the input of a random number generator. Giving different seeds to the generator will yield different layouts. ABC Path is a puzzle game in which one should position the letters from "A" to "Y" in a 5*5 grid based on clues. It is featured on brainbashers.com. ABC Path Generator makes use of depth-first-search to find usable final paths, and then assigns the clues for it, also using DFS.
ABC Path Solver is a Perl program and library that automatically solves an ABC Path game while giving the reasoning. ABC Path is a puzzle game in which one should position the letters from "A" to "Y" in a 5*5 grid based on clues. It is featured in brainbashers.com. ABC Path Solver uses a mixture of deduction and solving by trying several branches, which should allow it to solve all initial boards.
ACFTools is a utility for manipulating X-Plane flight simulator aircraft and weapon models without using its Plane Maker. It can decode both Apple and Intel ACF/WPN formats into plain text files with a syntax similar to C, which can be edited and then re-converted into binary data. It is able to extract almost complete 3D models of aircraft (fuselage, floats, tanks, wings, stabs, propellers, engines) and write it in AC3D modeler format. Edited 3D parts can then be merged into plain text and consequently converted into binary ACF files.
ADJE WebMail is a set of Perl CGI scripts which provide a Web interface to existing email accounts on any POP3-compliant email server. The software provides a complete interface, including encoding/decoding attachments, email and URL markup in received emails, and an address book for each user.
ADMLogger is a log analyzing engine. Using this core, users could easily build upon it with plugins. With very little Perl programming knowledge, it may become a powerful tool in a System Administrator's toolbox. ADMLogger creates email reports that can be formatted plain text or full HTML, which is up to the plugin designers to support. The main system has an HTML preference, so if your plugin ignores it, so be it. ADMLogger will also remove all filtered entries from the main syslog file into a second file so your other entries are more noticable.
AFT (Almost Free Text) is a document preparation system. It is mostly free form, meaning that there is little intrusive markup; AFT source documents look a lot like plain old ASCII text. It has a few rules for structuring your document, more to do with formatting your text than embedding lots of commands, and it produces all types of output (HTML, XHTML, LaTeX, roll-your-own XML, etc.). All that needs to be done is to edit a rule file. You can even customize your own rule files for specialized output.
AI::Prolog is a predicate logic engine implemented in pure Perl. In predicate logic, instead of telling the computer how to do something, you tell the computer what something is and let it figure out how to do it. Conceptually, this is similar to regular expressions. The AI::Prolog distribution contains a Prolog shell called aiprolog and two short adventure games, spider.pro and sleepy.pro.
AI::GA implements a (hopefully) generalized genetic algorithm. It does this by using an array of allowed tokens as individuals. The user has to provide a fitness function. There, the actual representation is implemented. If you have a string of chars, you can simply join them. If you want to have real numbers, you should probably use a bitwise representation and calculate the real values in your fitness function.
