Hi @afattahi. You can find that information if you use GMP functionality. I have attached a zip file containing a small AIMMS library. After unzipping the zip file you can include the library in your AIMMS project using the Library Manager. The library contains a procedure that can be used to find the smallest and largest coefficient (in absolute sense) in a generated math program. It will print that information to a file.

For a math program MP you can call this procedure as:

solve MP;
gmmc::GetMinMaxCoefs( 'MP' );

Here ‘gmmc’ is the prefix of the library. You do not have to solve the math program first; it is sufficient to generate it, i.e., you can also use:

myGMP := GMP::Instance::Generate( MP );
gmmc::GetMinMaxCoefs( myGMP );

The procedure contains two optional arguments, with a default of 0, which can be used to print all coefficients that are smaller than the first threshold value or larger than the second threshold value. For example:

gmmc::GetMinMaxCoefs( 'MP', 1e-5, 1e5 );

This will print all coefficients smaller than 1e-5 or larger than 1e5.

Note 1: The library uses an undocumented procedure, namely GMP::Coefficient::GetMultiSpecial which is much more efficient than using GMP::Coefficient::Get (in a for-loop).

Note 2: AIMMS can automatically scale the model for you if you use the Solvers General option ‘Scale model’. This option has been introduced in AIMMS 4.78.
