AMPL is a language and system for formulating, solving, and helping understand mathematical programming problems (of minimizing or maximizing a function subject to constraints). The AMPL book, details of which appear in "ampl.info from ampl", explains AMPL in much more detail and provides many examples. See also "index from ampl", "readme from ampl/solvers", and the AMPL Web site at URL http://www.ampl.com/ampl/ The material in this directory and its subdirectories, like other netlib material, is available by E-mail, ftp, and World Wide Web browser. For more details, send the 2-word E-mail message "send readme" to netlib@netlib.bell-labs.com . If you use the netlib ftp server netlib.bell-labs.com, appending ".tar" to a directory name will get you a tar file of the directory and its subdirectories. For example, in directory ftp://netlib.bell-labs.com/netlib/ampl if you say binary get solvers.tar you will get a tar file of the solvers directory and all of its subdirectories. (The files in these directories are .gz files; the gzip binaries in directory /netlib/gnu/gzip can uncompress .gz and .Z files.)
