Keep in mind that it is still your responsibility to ensure that your downloading and usage of the third party components conforms with their licenses. On Windows, the names are \texttt{libhsl.dll}, \texttt{libpardiso.dll}, and \texttt{PATH}. Download and the extract the minos solver. Under some circumstances, this fails, and you might have to re-issue the command, or omit the {\tt -j} flag. \item If you want, you can run a short test to verify

Is adding the ‘tbl’ prefix to table names really a problem? Now when I try to solve my instance I get: >> >> --------------------- >> Presolving Time: 4.21 >> >> time | node | left |LP iter|LP it/n| mem |mdpt |frac |vars This tutorial is not intended as a guide to formulating models in AMPL.

You can either download the code using \texttt{svn} (the \textit{subversion} client) or \texttt{git} or simply retrieve a tarball (compressed archive file). For certain compilers we enabled default values for this, but those might not exist or be wrong for your compiler. Instead, you can just put a shared library called \texttt{libhsl.so} or \texttt{libpardiso.so} into the shared library search path, \texttt{LD\_LIBRARY\_PATH}. Ampl Solver For this, the directories with the \Ipopt source must not have any configuration and compiled code. \subsection{Installation on Windows}\label{WindowsInstall} There are several ways to install \Ipopt on Windows systems.

The executable flag (chmod +x) is true. Ampl Can't Find File This comes in handy when you want to compile the code with different compilers, compiler options, or different operating system that share a common file system. Then you do the following steps (assuming here that you don't have any complications with firewall settings etc - in that case you might have to choose some connection settings differently): https://groups.google.com/d/topic/ampl/dSoABs1U6Mo From \url{http://www.pardiso-project.org}, you can obtain a limited time license of Pardiso for academic or evaluation purposes or buy a non-profit or commercial license.

We would be very happy to hear about your experiences. \subsection{Prerequisites}\label{sec:prerequisites} In order to build \Ipopt, some third party components are required: \begin{itemize} \item BLAS (Basic Linear Algebra Subroutines). As well, you can link your problem statement with \Ipopt using interfaces for C++, C, or Fortran. \Ipopt can be used with most Linux/Unix environments, and on Windows using Visual Studio But it still doesn't work and the AMPL shows me that error message (cannot find "minos")... –Roman Dryndik Mar 16 '13 at 21:16 @RomanDryndik Did you try the option Changing the solvers doesn't help.

Note: MUMPS will perform better with METIS, see Section~\ref{sec:METIS}. Note: The {\tt configure} script is not able to automatically determine the C++ runtime libraries for the C++ compiler.
