     The UCLA-SFINX, a "neural" network simulator is now in  pub-
lic domain.  UCLA-SFINX (Structure and Function In Neural connec-
tions) is an interactive neural  network  simulation  environment
designed  to  provide  the  investigative  tools for studying the
behavior of various neural structures. It was designed to  easily
express  and  simulate the highly regular patterns often found in
large networks, but it is also general enough to  model  parallel
systems of arbitrary interconnectivity.

     UCLA-SFINX is not based on any single neural  network  para-
digm  such as Backward Error Propagation (BEP) but rather enables
users to simulate a wide variety of neural network models.  UCLA-
SFINX has been used to simulate neural networks for the segmenta-
tion of images using textural cues, architectures for  color  and
lightness  constancy,  script character recognition using BEP and
others.

     It is all written in C, includes an X11 interface,  and  it
has  been  ported  to HP 9000 320/350 workstations running HP-UX,
Sun workstations running SUNOS 3.5, IBM RT  workstations  running
BSD  4.3,  Ardent  Titan workstations running Ardent UNIX Release
2.0, and VAX 8200's running  Ultrix  2.2-1.   To  get  UCLA-SFINX
source  code  and  documentation (in LaTeX format) follow the in-
structions below:


1.   To obtain UCLA-SFINX via the Internet:
