'''SNNS''' (Stuttgart Neural Network Simulator) is a [neural network simulator](/source/Neural_network_software) originally developed at the [University of Stuttgart](/source/University_of_Stuttgart). While it was originally built for [X11](/source/X11) under [Unix](/source/Unix), there are [Windows](/source/Microsoft_Windows) ports{{Citation needed|date=September 2018}}. Its successor [JavaNNS](/source/JavaNNS) never reached the same popularity.

==Features==

SNNS is written around a simulation kernel to which user written activation functions, learning procedures and output functions can be added. It has support for arbitrary network topologies and the standard release contains support for a number of standard [neural network](/source/neural_network) architectures and training algorithms.

==Status==

There is currently no ongoing active development of SNNS. In July 2008 the license was changed to the [GNU LGPL](/source/GNU_LGPL).
