Subdirectories of this directory contain student versions of the AMPL processor for the platforms indicated in the table below. When time and opportunity permit, we may add some solvers to these directories. Executable binaries have been compressed with gzip (as indicated by the suffix ".gz"). Transfer them in binary mode, and uncompress them by executing gzip -dN *.gz If need be, you can get copies of the gzip binaries we used or of the source we used to generate them from ftp directory ftp://netlib.bell-labs.com/netlib/gnu/gzip .
