The ECLiPSe Constraint Logic Programming System is designed for solving combinatorial optimization problems, for the development of new constraint solver technology and their hybrids, and for the teaching of modelling, solving and search techniques.

DD Thought Tickler is a thinking process recorder. It is a kind of vector graphics editor and idea processor. It has new function not ever known. It records your thinking process, by memorizing every steps that you've operated on this tool.

As software architect, you create a set of diagrams describing use-cases, requirements, structural views, behavioral and deployment views. crystal_facet_uml keeps element names and element hierarchies consistent. It exports diagrams in svg, pdf, ps and png formats to be used in text processing systems like docbook, html, latex. This tool runs on your local PC and is based on glib, gdk, gtk, cairo, pango, sqlite.

EcoLab is a C++ based Agent Based Modelling system, with emphasis on high performance computing for scaling to large simulations.

A component based programming framework. This project is aimed to support various target frameworks. A wxWidgets based GUI application is the major sample which also provides rapid database GUI design with UML import and export (db reverse engineering).

The ADG library (Automatic Drawing Generation) is a set of functions focused on automating the drawing of mechanical parts. It is not a CAD system but a GObject-based library where a custom application can put common CAD entities such as paths, hatches and dimensions, to automatically create technical drawings. A demo application is provided in order to show the capabilities of the canvas. Although it is possible to interact with the library directly in C (that is what the adg-demo program is doing), the canvas is expected to be used from higher level languages, much in the same way as what done in the GNOME stack. Lua bindings based on LGI are already provided out of the box. The adg-lua project, downloadable from the "Files" section, provides Lua programs and demos that leverages these bindings.

The Introspector enables the programming tools that deal with source code such as the compiler to communicate in a standard and neutral manner reducing the accidental cost of programming. http://github.com/h4ck3rm1k3/

Adaptive Simulated Annealing (ASA) is a C-language code that finds the best global fit of a nonlinear cost-function over a D-dimensional space. ASA has over 100 OPTIONS to provide robust tuning over many classes of nonlinear stochastic systems.

PEP is a modelling and verification framework for parallel systems, providing a large number of different modelling languages and verification techniques (e.g. SDL, Petri nets and model checking)

SPE is a python IDE with auto indentation&completion,call tips,syntax coloring&highlighting,uml viewer,class explorer,source index,todo list,pycrust shell,file browsers,drag&drop,Blender support.Spe ships with wxGlade,PyChecker and Kiki.

Support for more productive Model Based Systems Engineering, following the recommendations in the Cookbook of the INCOSE SE2 Challenge team http://mbse.gfse.de The Plugin for the MagicDraw modelling tool provides support for model based document generation which ties together system model and documents to keep them up to date and consistent, using a AWYSIWYG editor in MagicDraw. It provides basic support to model variants and extract variants from a system model. It provides support to generate organizational structures according to the SE2 Cookbook recommendations. It provides basic pattern based support to reason on a system model, for example to extract numbers like total power, cost, power consumption for a given product tree The MBSE plugin for MagicDraw requires MagicDraw 17.0 SP4 or higher with an installed SysML plugin 17.0 SP5 or higher. Installation instructions can be found in the file ReadMe.txt in the download area as well as the corresponding UMs.

Coral is a tool and a development platform to create and transform models and modeling languages. It can be used to edit UML models, to develop editors for other modeling languages and to implement MDA and QVT-like model transformations.

Pretty Damn Quick (PDQ) analytically solves queueing network models of computer and manufacturing systems, data networks, etc., written in conventional programming languages. Generic or customized reports of predicted performance measures are output.

A tool for people interested in Special Relativity. Can introduce you to some basics, as the transformations and the 4-vectors. Examples, illustrations and some exercises will be included. With some time, effort, and space on the desk, you can master it.

A set of tools and utilities that allow development teams to practice code generation techniques in a scalable and extensible manner. This is based on the style of code generation found in Ruby on Rails.

FOML is an expressive logic rule language that supports object modeling, analysis, and inference. It naturally supports model-level activities, such as constraints (extending UML diagrams), dynamic compositional modeling, analysis and reasoning about models, model testing, design pattern modeling, specification of Domain Specific Modeling Languages, and meta-modeling. FOML can reason about: 1. The model meta-data (meta-model level reasoning, or syntax reasoning) 2. Data level: reason about a model and its data (instance model, i.e., diagram) FOML is built as a semantic layer on top of PathLP - a compact logic rule language of guarded path expressions, an adaptation of a subset of F-logic.

Fiona is a tool to automatically analyze the interactional behavior of a given oWFN. It provides two techniques: it checks for the controllability of the given net by computing the interactiong graph and it calculates the operating guideline for the net.

A graphical interface programming system allowing the visualization of code and capability to generate threaded code. The user constructs code segments using visual boxes. The program flow is represented as links between the boxes.

Custom built java web browser

Interactive PHP shell Create an interactive environment to debug php line by line. It enables you to execute php code as if it were a command line in a similar setting to bash and psh (perl shell).

MASyV (Multi-Agent System Visualization) enables one to write agent-based models/cellular automata, eg. in C, visualize them in real time & capture to movie file with MASyVs GUI & message passing lib. Includes examples: Hello World, ants, viral infection

An integrated CASE system that: • Supports multiple views and stages of project development – from keeping track of reference documentation to analysis/design modelling, to project implementation, roll-out and tracking the project-related issues. • Supports distributed development of projects by multiple participants, while proactively enforcing access control rules and auditing changes. • Is available on all platforms where development takes place (Windows, Unix/Linux, MacOS, Solaris, etc.) • Offers ideological and conceptual integrity across all facilities. By adapting a new approach to CASE tool architecture (integration at repository level and developing a component-based CASE system instead of a monolithic tool) an entirely new species of tools can be brought into a useful existence – an integrated environment where all project-related activities can be performed efficiently.

(Pre-Alpha) Cross-Platform ERD to Database Design Tool built in Java. Currently Supports PostgreSQL. Not Feature-Complete.

Recito is a graphical modeling and process simulation platform.
