NAME
snns - neural network simulation package SNNS

SYNOPSIS
xgui [options] batchman [options] snns2c [options]

DESCRIPTION
SNNS (Stuttgart Neural Network Simulator) is a simulator for neural networks developed at the Institute for Parallel and Distributed High Performance Systems, at the University of Stuttgart since 1989. The goal of the project is to create an efficient and flexible simulation environment for research on and application of neural nets. The SNNS simulator consists of four main components: Simulator kernel, graphical user interface, batch execution interface batchman(1), and network compiler snns2c(1). The simulator kernel operates on the internal network data structures of the neural nets and performs all operations on them. The graphical user interface xgui(1), built on top of the kernel, gives a graphical representation of the neural networks and controls the kernel during the simulation run. In addition, the user interface can be used to directly create, manipulate and visualize neural nets in various ways. Complex networks can be created quickly and easily. Nevertheless, XGUI should also be well suited for unexperienced users, who want to learn about connectionist models with the help of the simulator. An online help system, partly context-sensitive, is integrated, which can offer assistance with problems. An important design concept was to enable the user to select only those aspects of the visual representation of the net in which he is interested. This includes depicting several aspects and parts of the network with multiple windows as well as suppressing unwanted information.

BUGS
None. There are only features. Its also a feature, that some of the man pages are not implemented yet.
