Component_Delphi_GA

The present work proposes a non-visual component developed in Object Pascal programming languages, for Genetic Algorithms called "TGAlgorithm". Developed in a fully object-oriented framework, the Component exploits this feature to facilitate its extension to genetic algorithms and specific problems, be they single-purpose. In this work an example of the use of "TGAlgorithm" for an implementation of a genetic algorithm mono-objective is presented.

System

QuickCrt

Based upon my 20+ year old super fast QCrt text mode display driver, QuickCrt is an event driven object-oriented framework for rapid application development using Turbo Pascal 7.0 for DOS. Completely self contained, it uses no 3rd party or original Borland units (excluding the built-in System unit). It uses no Turbo Vision and is more like Delphi minus the drag and drop. It has support for String formatting, Custom text fonts, Themes, Keyboard mappings, Config files and Multiple languages baked into it. However, this initial version is more of a "Proof of Concept" and engine for PGME. Rather than an actual project. It has some serious limitations. Since it was built in a "vacuum" with no pre-planning, it is a little bit of spaghetti code. Also, it doesn't support real windowing, multi-tasking or draw behind visible objects. QCrt 9 is currently under development. It is a complete rewrite in assembly with TP wrappers. It is being hosted at http://github.com/LoopZ/QCrt

Snap7

Snap7, through three specialized components: Client and the inedited Server and Partner, allows you to definitively integrate your PC based systems into a PLC automation chain. Designed to transfer large amounts of hi-speed data in industrial facilities, it scales easily, down to small Linux Arm boards such as Raspberry PI. Hi level object oriented wrappers are provided, currently C/C++, .NET/Mono, Pascal, LabVIEW, Python with many source code examples. Very easy to use, a full working server example is not bigger than the “Hello world”. Many projects/makefiles are ready to run to easily rebuild Snap7 in any platform without the need of be a C++ guru. Very detailed documentation provided.
