Developer - Smart Pointers

smart_ptr is a smart pointer policy class that can use different ownership logic and semantic polices, which allows the developer to get the best performance and/or interface for a particular requirement.

The smart_ptr class can be used with STL containers to create containers of smart pointers, moreover it can be used to create a container of abstract based objects via smart_ptr. In general, smart_ptr is faster than boost::shared_ptr. When used with STL containers, the smart pointer is faster than the boost pointer containers, and more generic.

GTL - The Graph Template Library

The Standard Template Library (STL) is supposed to become a part of the C++ standard library and therefore is an ideal basis when writing portable programs.

Unfortunately, STL has no support for graphs and graph algorithms. However, graphs are widely used to model complex relational structures.

Since we are intensively working with graph algorithms and Graphlet, we decided to implement GTL, a graph library based on STL. For the design of GTL's API the API of LEDA has served as a basis. GTL contains the classes needed to work with graphs, nodes and edges and some basic algorithms as building blocks for more complex graph algorithms. Further algorithms are under work.

GAGS - C++ class library for Genetic algorithms

It includes classes for chromosomes and populations.

Library:binary chromosome representation. Genetic operators: mutation, xOver (n-pt and uniform), remove/reinsert. Selection operator: steady state, tournament, roulette wheel. Perl and/or tcl/tk graphic front-end. Graphics through gnuplot. Training from file.

Application generator: it needs only an ANSI-C definition of the fitness function. It's parsed, and a program that runs a GA on it is generated.

libpropc++ - Add properties to C++ (widget.color = "red";)

Template library for properties in C++ (like this:widget.color = "red"; to change widget color).

class Widget { ... Color get_color(); void set_color(Color value); prop::Property<Widget, Color, &Widget::set_color, &Widget::get_color> color; ... };

JPTUI - Textual user interface for DJGPP

Textual user interface for DJGPP 2, v4.0e

JPTUI is an object-oriented textual user interface. Designed for C++, it provides a simple to use application programming interface. JPTUI is available for DJGPP 2 and Borland C++ 4.

I am told that this library is no longer on Simtel, but there is an older version stil available via ftp from a different site.

libLCS - Library for Logic Circuit Simulation

libLCS is a hardware description library in C++ aiming to be as powerfull and easy as the Verilog HDL. It currently supports logic gates, flipflops, clock, and facilitates delays, continuous assignments and variable value dumping into VCD files.

libLCS is a library for Logic Circuit Simulation developed in 100% c++. The ultimate aim of LCS is to become a thorough hardware description library, matching the functionality of the Verilog hardware description language, while keeping the usage (and syntax) as intuitive as possible. Currently, it supports simulation of digital systems containing logic gates, flipflops, clock, user defined modules, and facilitates propogation delays, continuous assignments and dumping value changes into VCD files.

Fast Light Toolkit - GNU LGPL GUI toolkit for X11 and Windows

FLTK (pronounced "fulltick") is a LGPL C++ graphical user interface toolkit for X (UNIX®), OpenGL, and WIN32 (Microsoft® Windows® NT 4.0, 95, or 98). It is currently maintained by a small group of developers across the world with a central repository in the US.

FLTK was originally created to build in-house applications at Digital Domain for image processing and 3D graphics. The original author, Bill Spitzak, received permission from Digital Domain to release it to the public domain in the hopes that it could be used to make better, faster, and nicer-looking UNIX programs. Digital Domain has since withdrawn support for FLTK, but Bill is still able to work o!n it from time to time. FLTK was designed to be small and modular enough to be statically linked. FLTK also works fine as a shared library and has started being included on Linux distributions.

Here are some of the core features unique to FLTK:

GiNaC - Symbolic computation embedded in C++

GiNaC is an iterated and recursive acronym for GiNaC is Not a CAS, with CAS standing for Computer Algebra System. It is designed to allow the creation of integrated systems that embed symbolic manipulations together with more established areas of compute r science (like computation- intense numeric applications, graphical interfaces, etc.) under one roof. It is distributed under the terms and conditions of the GNU general public license GPL.

It implements a class hierarchy with the basic classes needed to create symbolic expressions, including abritrary length/precision numbers (drawing from the CLN library). The classes provide basic symbolic manipulations as well as memory management through reference counting, disk-I/O, etc. Using the Cint C/C++ interpreter it is even possible to use it in an interactive manner.

It is written in standard C++ and should compile on any compliant compiler. Since it has to be linked with CLN, however, it is somewhat tricky (but not impossible) to do so on other compilers than GCC.

Lodestar Database - Client/Server - High performance, non-relational database engine

Lodestar Database is a super fast, non-relational database engine which comes in either single user or network enabled, multi-user client/server versions. The network version comes with either a Novell server or an NT server with clients for Windows 95/98/2000 and Windows NT. Both versions have libraries for Borland C++, Delphi, C++ Builder and Visual Basic.

Lodestar Database has been in use for 10 years in the financial industry and has contributed to huge run time improvements in Credit Union software used throughout the US, but is just now being released to the public as shareware. Credit Unions with as many as 10 branches and thousands of users are currently using our database engine with sub-second response times. Statement runs are 35 minutes for a 35,000 member credit union with over 100,000 accounts and can be run while the credit union is open with virtually no degradation in online response time.

Elemental - Elemental is a very young C++ library

I am told this library is now obsolete.

Unfortunately, the author doesn't tell me what the library is for, or what ot does. All he says is:
Like most other C++ libraries, it is Object Oriented. Like few other C++ libraries, it is Generic. Unlike any other C++ libraries, its design includes an abstract layer. In this layer, all classes are abstract, and all of the types that appear in the interfaces to those classes are also abstract.

Elemental is distributed under a license which is remarkably similar to the Netscape Public License. I welcome comments and suggestions, but working code are better! (There is lots of juicy designing and coding left to do.)

GECOOL 2.1 - A reworking and enhancement of Texas Instrument's "C++ Object Oriented Library"

By some programmers at General Electric.

Also available is JCOOL. Its main difference from COOL and GECOOL is that it uses real C++ templates instead of a similar syntax that is preprocessed by a special 'cpp' distributed with COOL and GECOOL.

Some users behind "firewalls" have had difficulty accessing the ftp site.

ImageLib - An Image Processing C++ Class Library

ImageLib is a C++ class library providing image processing and related facilities.

The main set of classes provides a variety of image and vector types, with additional modules supporting scalar and vector quantisation, wavelet transforms, DCT transforms, and simple histogram operations.

Tested on Solaris and FreeBSD, but should work with most other UNIX versions. Most features are not operating system specific.

FFTPACK++ - C++ version of FFTPACK

FFT_Pack is a C++ wrapper for FFTPACK complex routines using LAPACK++ Matrix and Vector classes. FFTPACK routines were converted to C using f2c and also modified to use double precision complex using -r8 to f2c.

Most of this code was lifted directly from GNU OCTAVE v1.1.0, hence the copyright notice at the top.

The forward FFT takes you to freq domain (ala direction == -1), and backward the other way.

Passing LaVectorComplex/Double or LaGenMatComplex/Double with one dimension set to 1 will implicitly perform 1D FFT on the data.

The members of the FFT_Pack class are declared static, since they really need no private member storage. There are two types of transform routines: ones that return a new complex matrix and the ones that change the matrix in place.
