3**********************************************************************
4
5There  are  a number of  problems  that  we know  about,  but which we
6haven't had time to fix yet. Among them are:
7
8- Some  HP machines have  problems with  the  bignet panel  for Jordan
9  networks. There have been several segmentations faults reported.
10
11- When  converting a  netork to C-Code with snns2c, special units will
12  be  ignored. This means,  that when  converting a  network  on which
13  input   pruning has been   performed, the resulting  C function will
14  accept only patterns with less input values.
15
16  Example: A  26-10-35 network was pruned, and  consequently lost 3 of
17  its input units (Note that they are still represented in the network
18  file  as  "special input"  units).   After converting the  resulting
19  network  to C code  you  can call  this  function only with 23 input
20  values. Which of the original 26 values have  to be skipped is to be
21  determined by the user!

25                           REPORTING BUGS
26**********************************************************************
27
28If you really need to report a bug you should run
29
30        make bugreport
31
32in <SNNSDIR>. This command ensures, that your Makefiles are up to date
33and prints out all critical definitions.  If you see, that the SNNS is
34reconfigured during this operation, you must recompile SNNS and check,
35if the   bug is still  there  before complaining  about problems. Also
36refer to Readme.install  to learn more  about how to change C-compiler
37usage and compile flags.
38
39The output  from the  above  command should be   included in your  bug
40report, so we don't need to ask you about your system characteristics.
