ALGENCAN 1.0 AMPL interface
Note that this interface corresponds to an old
version of ALGENCAN! Click here to
download the ALGENCAN latest version (including all the
interfaces).
-
algencanma.run
- This file contains an AMPL script that
loads the problem model and then calls the optimization
solver (GENCAN for bound-constrainted problems and ALGENCAN for general
nonlinear programming problems) to solve the problem.
-
toyprob.mod
- This file contains the model in AMPL
of a very easy problem. This is the file that the user should
modify to solve his/her own problem.
-
amplwrapper.c
- This is the file responsible for the
interface between AMPL and C/C++.
-
amplwrapper.h
- amplwrapper header file.
-
cfortran.h
- This is the file responsible for the
interface between C/C++ and Fortran.
-
Makefile
- This (optionaly) file can be used to easily
compile the codes using the make command.
Quick start
| 1) | Copy the 6 files above. |
| 2) | Compile typing
make or, manually, typing
g77 -O4 -c -xf77-cpp-input -DAMPL algencan.f
gcc -O4 -c -Df2cFortran -I$AMPLDIR/solvers amplwrapper.c
g77 -O4 -ldl -lstdc++ algencan.o amplwrapper.o \
$AMPLDIR/solvers/amplsolver.a -o algencan |
| 3) | Enter into AMPL and type
include algencanma.run.
| | Obs1: |
To use this interface you need to have downloaded
ALGENCAN 1.0. |
| Obs2: |
It is assumed that (i) the environment variable
AMPLDIR points
to the directory where AMPL is installed and that (ii) you have
downloaded file solvers.tar from the
AMPL page
at Netlib and (following the instructions in the README file)
built the file
$AMPLDIR/solvers/amplsolver.a.
| | Obs3: |
Be sure that the current directory is in the PATH enviromental
variable, so (at Step 3) AMPL will be able to find the executable
file algencan generated at Step 2. To
add the current directory to the path in a Linux platform, type
export PATH=$PATH:.. |
