---+ AMPL Guide

AMPL stands for "A Mathematical Programming Language". It is used to describe [[MathematicalProgramming][mathematical programmes]].

AMPL is a commerical software package from [[https://www.alcatel-lucent.com/wps/portal/BellLabs][Bell Laboratories]] and is also distributed by [[https://www.ilog.com][ILOG]] along with the mixed-integer linear programme solver [[https://www.ilog.com/products/cplex/][CPLEX]].

For more details see the main AMPL website:

[[https://www.ampl.com][www.ampl.com]]

and there is a good, fairly comprehensive book on AMPL:

[[https://www.ampl.com/BOOK/index.html][AMPL: A Modeling Language for Mathematical Programming]]

However, you don't need to pay for AMPL right away! There is a limited functionality [[https://www.ampl.com/DOWNLOADS/index.html][student version]] which also provides [[https://www.ilog.com/products/cplex/][CPLEX]] (the mixed-integer linear programme solver from [[https://www.ilog.com][ILOG]]) and [[https://www.sbsi-sol-optimize.com/asp/sol_product_minos.htm][MINOS]] (the nonlinear programme solver from the [[https://www.stanford.edu/group/SOL/index.html][Systems Optimization Laboratory]] at [[https://www.stanford.edu][Stanford University]]). This Student Version will have enough functionality for most of the problems you will encounter in the case studies on the [[Trash.OpsRes_ForumWebHome][OpsRes Web]].

You can also use AMPL over the web at the [[https://www.ampl.com/TRYAMPL/index.html][AMPL web interface]] or you can use AMPL as an interface to many diferent optimisation solvers at the [[https://www-neos.mcs.anl.gov/][NEOS Server for Optimization]].

*Notation* In this AMPL Guide we will enclose required user input with =&lt;= and =&gt;= and _optional_ user input with =&#91;= and =&#93;=, e.g.,
<pre>
var &lt;varname&gt; &#91;vartype&#93;;
</pre>
means that the user must supply =varname= (the variable name), but has the option to either specify =vartype= (the type of variable) or not (the type will default to a real variable).
