[Couenne] Is there any free tool which can produce .nl file ?

[Pietro Belotti]

Lili,

I know of no free AMPL parser. However, if you are interested in a 
modeling language for mixed integer linear problems, you may want to try 
ZIMPL (http://zimpl.zib.de).

If, instead, you want to solve nonlinear problem formulated with AMPL, you 
may try the Neos server for optimization 
(http://neos.mcs.anl.gov/neos/solvers), where you can use many solvers and 
submit an AMPL .mod file without restrictions on the number of 
constraints/variables.
