Create Local Solver Configuration¶
Normally, the list of solvers available via the solver configuration screen is the same for all projects opened with the same version of AIMMS. In this article, we’ll see how to overrule the solvers that are available for your current project.
You can change the default solver for each type of mathematical program via the
solver configuration screen (accessible from the Settings
You can temporarily overrule this default
by modifying the
parameter or with a
where clause with the solve statement.
Read more details about how to do so in the article Change the Default Solvers Used.
Solver Configuration File¶
You can overrule the default list of solvers for a specific project by
providing a plain text file named
An example of what it may contain is the following:
1 2 3 4 5
! Format AIMMS380 ! solver name / dll name / model types for which solver is the default CPLEX 10.1 / libcpx101.dll / CPLEX 12.4 / libcpx124.dll / CPLEX 12.5 / libcpx125.dll / LP MIP QP MIQP QCP MIQCP
Any line starting with a ! is considered a comment line. The different
columns give the name of the solver, the DLL to use, and for which type
of mathematical programs this solver is the default solver.
If you save the above into a file named
solvers.slv in your project directory, the
next time you start this project you will only see the three CPLEX
solvers in the solver configuration screen.
Exporting from AIMMS¶
Alternatively, open the solver configuration screen and press the
Export button to create a
solvers.slv file in your current project
A notification appears when the solver
configuration has been successfully exported to a local solver
This local solver configuration ensures that your project always uses a specific version of a solver, regardless of whether your end user has this solver version in their solver configuration.
solvers.slv file is present in your project directory, any changes
you make in the solver configuration screen is saved in this
This configuration applies only to that project and not globally for the AIMMS version you are using.
