The AMPL website contains the first chapter of the AMPL book, a collection of frequently asked questions, and a list of all the cplex options available in AMPL.
Note that if you use the command line interface with Windows and you use Word to create and edit the files, Word will add txt to the end of a filename when stored as a text file. For example, if your model is called zoff.mod and you created it and stored it using Word, the file will be called zoff.mod.txt. To read it into AMPL, you will need to use the command
ampl: model zoff.mod.txt;
You must have an RPI account to be able to use the size-unrestricted versions.
Installing AMPL and CPLEX on your personal computer: Our license now allows you to install the size-unrestricted versions of these programs on your own machine. Once you've installed the programs in Windows XP, you run them from a command prompt window. In Linux or in Mac OS X, they run in a terminal window. The program OPL is also available, as an alternative to AMPL. OPL is an ILOG modelling language and environment that has a user interface that is more user-friendly than AMPL. You can even run them from off-campus as long as you have Cisco VPN running.
To use the size-unrestricted version of AMPL on RCS, you need to follow these instructions.
AMPL is not an IBM product and so our version of AMPL cannot be used with versions of CPLEX downloaded through the acadmic initiative, as far as I know. A downloaded version of CPLEX can either be run as a stand-alone program or called from other software written in C or C++ or Matlab, for example.
