PajFit (Parallel Job Fit) is simple simulator for scheduling parallel jobs. It has a GUI to see the scheduling output. It supports rigid and moldable jobs, as well as advance reservations and jobs with hard deadlines.
STOCHSIM is a stochastic simulator for biochemical reactions. The particles are represented as individual software objects which react according to probabilities derived from concentrations and rate constants. Simple spatial structures can be built.
EventListener is a simple and efficient C++ framework for propagating Events in graphical interfaces or numerical codes, using Listener pattern. Filtering and blocking of events is possible. This package does not use any other lib.
Visual Turing Machine is a tool for visually designing Turing machines. This means no coding in abstract scripting languages, but simple point&click design. It uses the a..z symbol set, plus the "empty" # symbol, and also simulates an infinite tape.
The Simple Interface for Global Optimization Algorithms allows the specification of arbitrary search/optimization problems, solving of these problems, and the specification and implementation of optimization algorithms like evolutionary algorithms.
SpiceX is a simple schematic capture program for graphical interaction with Spice-based electronic simulation cores, i.e., placing components, wires and test points. SpiceX creates NETLISTs and runs simulations directly from the GUI.
It started as a simple physics API for educational purposes, but now its development is clearly focused on gaming and will be incorporated to a next-gen engine.
Orbit is currently a simple orbital simulator for simple circular orbits. It ultimately aims to be a general gravity machine, which will allow the instant creation of galaxies.
jversim is a traffic simulator. Simulated networks can have one- or two way roads, destinations and simple crossroads. It shows a graphical simulation and problematic areas. It can be used as a toy or for learning about discrete simulations.
FreeMarket is a software package for running simple virtual prediction futures markets that uses the renowned PHP scripting language and MySQL database tools. It is designed for educational and medium-scale research applications.
rsim is a simple discrete-event communications network simulator initially developed to test routing protocols for undersea acoustic modem networks. If done well then rsim will eventually be a good replacement for "ns2".
This program tries to simulate a simple computer. Users can write assembly programs for this simulator, which can be loaded and interpreted as instructions. An OS is also included with it, providing process dispatching and file system functions.
jFAST is a simple finite automata (FA) graphical simulation utility; it is designed to feature simple mechanisms for creating, editing, and simulating FA. jFAST is ideal for use by students, instructors, and self-guided explorers alike.
Partgen is a simple particle system generator and simulator. It's intended to have a 3D scene description language, and batch processing mode. Support for some scripting languages like ruby is also planned
JSys is a simple to use graphical package for simulating continuous dynamical systems. It was created for use in a first level undergraduate introduction to systems thinking for students of Information Technology and Information Systems.
Simulator for large neuronal networks using leaky INF as its basic element. Simple few line scripts will enable rapid creation of large networks with different connectivities. Aimed at researchers interested in quickly testing large networks of neurons.
A set of R functions (www.r-project.org) for simple hydrological models, based on linear and non-linear storages, MC simulation and multi-objective evaluation. The code provided here is aimed to be transformed into a proper R package at some point.
MODANS is a set of specifications that provides a simulation framework for Inter-Vehicular Networks (DTN). The project consists of a set of Java interfaces and it comes with some simple implementations and a simple Graphical User Interface.
Simple GUI tool for creating and manipulating WSN topologies
TOPO is a simple tool that allows the user to create and manipulate arbitrary Wireless Sensor Network (WSN) topologies without worrying about the anomalies that could arise using a text-base topology description. It is fast and easy to use and can accelerate small scale projects such as network simulation.
The tool is still undergoing development stage and is open to extension.
